ADINA 8.8.4 has been released.

These Useful Hints and Issues, while reported for the specific version 8.8.4, are usually also applicable to the ADINA versions 8.8.3, 8.8.2, 8.8.1 and 8.8.0.



Useful Hints and Issues
Regarding the Use of the ADINA System, v. 8.8.4

Issue No. 35, posted November 14, 2012

When using shell elements with the element birth-death feature, occasionally the porthole file cannot be loaded into the AUI. The AUI gives a message similar to

***ALERT: Unexpected data in ADINA porthole file, record 'OUTPUT-7' The loading of the porthole file is stopped.

There is no workaround. This bug is fixed in v 8.8.5.


Issue No. 34, posted November 14, 2012

The temperature results in ADINA TMC analysis are incorrect under the following conditions:

  • Bolt elements (either beam-bolt or 3D-bolt) are used, in a
  • Restart analysis, with
  • Nonlinear boundary convection or radiation element groups, and
  • Element groups loaded in-core.

As a workaround, use the element group out-of-core option, i.e. the command

DISK-STORAGE MEMOPT=EG-OUT.

This bug is fixed in v 8.8.5.


Issue No. 33, posted October 15, 2012

When plotting prescribed loads using bands, for example using the band plot variable (Prescribed Load: PRESCRIBED_PRESSURE), the prescribed loads are sometimes not plotted. This happens when a surface element group, such as a shell element group, contains elements with different nodal layouts, for example when there are 6-node elements and 9-node elements in the same group.

There is no workaround. This bug is fixed in v. 8.8.5.


Issue No. 32, posted October 15, 2012

The porthole file cannot be loaded into the AUI when the 3D-bolt feature is used in modal stress calculation.

The error message given is

ADINA porthole file mismatch, expected record 'MODSTRES', found record 'BOLTRES1' The loading of the porthole is stopped.

There is no workaround. This bug is fixed in v. 8.8.5.


Issue No. 31, posted October 15, 2012

This issue concerns the strain energy density calculation for the 3D solid element with the plastic-cyclic material model and the mixed u/p formulation.

For the special case in which the stresses and strains are constant within the element, the strain energy densities are correct. However, for the general case in which the stresses and strains vary within the element, the strain energy densities are incorrect.

In all cases, all other results, including displacements, stresses, plastic strains, etc., are correct. The issue concerns only the strain energy density calculation.

There is no workaround. The bug is fixed in v 8.8.5.


Issue No. 30, posted September 27, 2012

When using the Hermitian beam element with the elastic-plastic material model, rectangular cross-section and 2D element subtype (that is, the option of the beam to act in a plane) the number of integration points in the t direction must be set to 1 (which is the default), otherwise the program will give wrong results.

This bug is fixed in v. 8.8.5.


Issue No. 29, posted August 30, 2012

When a user-supplied material model is used for a large displacement analysis (i.e., by the total Lagrangian formulation), the reactions are calculated incorrectly; the stresses and strains are correctly calculated.

There is no workaround. This bug is fixed in v. 8.8.5.


Issue No. 28, posted August 15, 2012

When the LIST EDATA command is used to query an element group consisting of beam elements in a database from ADINA 8.7 or earlier, the AUI crashes or garbage is listed. The command works correctly when non-beam element groups in that database containing a beam element group are queried.

There is no workaround. This bug is fixed in v. 8.8.5.


Useful Hints and Issues
Regarding the Use of the ADINA System, v. 8.8.3

Issue No. 27, posted July 19, 2012

Deformation-dependent line follower loads are calculated and plotted incorrectly for line element (e.g., beam) loads when the auxiliary node is moving. If the auxiliary node is fixed, then the load is calculated correctly.

There is no workaround. This bug is fixed in v. 8.8.4.


Issue No. 26, posted July 19, 2012

There is a plotting error when using the MODELDEPICTION REFOPTION=REFTIME option. The error occurs when the following combination of options is used in the MODELDEPICTION command:

REFOPTION=REFTIME, ORIGINAL=YES, DEFORMED=YES, DISPOPTION=MAGNIFICATION or LENGTH

As a workaround, either plot the displacements without magnification, or plot the deformed mesh only without plotting the original mesh. This bug is fixed in v. 8.8.4.


Useful Hints and Issues
Regarding the Use of the ADINA System, v. 8.8.2

Issue No. 25, posted June 13, 2012

When making a band plot using a custom bandtable with VALUETYPE=PERCENT or MAXIMUM, the bands are displayed incorrectly during an animation.

There is no workaround. This bug is fixed in v. 8.8.3.


Issue No. 24, posted May 30, 2012

In the AUI Commands for ADINA manual, the description of the EDATA command (p. 9-40) is not sufficiently specific in the case of 6DOF spring elements. The parameters applicable for 6DOF-SPRING elements are listed as

eli    propertyseti    printi    savei    axi    ayi    azi    tbirthi    tdeathi    g0i    cidi
(for 6DOF-SPRING elements)

Currently, for 6DOF spring elements, ADINA only supports using the same properties for the spring elements within a given 6DOF spring element group. Thus, the parameter "propertyseti" is ignored and the corresponding "Property Set" column for the 6DOF spring element group is grayed out in the AUI "Element Data" dialog. However, users may still be confused by the above list of parameters, and mistakenly think they can use different properties within a 6DOF spring element group.

From ADINA 8.8.3 onwards, the use of different properties for the spring elements within a given 6DOF spring element group is supported. Thus, the list of applicable parameters for 6DOF-SPRING elements will be amended to read

eli    propertyseti    printi    savei    axi    ayi    azi    tbirthi    tdeathi    g0i    cidi
(for 6DOF-SPRING elements; propertyseti is ignored before version 8.8.3)


Issue No. 23, posted May 30, 2012

In a zooming analysis with shell elements in the model, the ADINA program stops with the following message

Mapping Interface Error, Icode=1036
*** ERROR NO. A1806 ***
Mapping Interface error, please contact ADINA R&D, Inc.

No results are produced.

There is no workaround. This bug is fixed v. 8.8.3.


Issue No. 22, posted May 21, 2012

The feature

MASTER SINGULARITY-STIFFNESS

does not work in conjunction with the non-symmetric sparse solver. This means that models with zero drilling stiffness cannot be solved with the non-symmetric sparse solver. For example, the analysis might stop with a 'zero pivot' message.

As a workaround, use the usual symmetric sparse solver. This bug is fixed in v. 8.8.3.


Issue No. 21, posted May 21, 2012

If the 3D-Iterative solver is used with the element birth/death glueing option and with contact, then the program might crash under certain rare circumstances.

As a workaround, use the sparse solver. This bug is fixed in v. 8.8.3.


Issue No. 20, posted May 21, 2012

If the gluemesh definitions are not defined in sequential order without gaps, then the AUI might give an error message when plotting the gluemeshes.

For example, if the gluemesh definitions are in the order

GLUEMESH 5 GLUEMESH 2 ...

or in the order

GLUEMESH 1 GLUEMESH 3 ...

the AUI might give an error message when plotting the gluemeshes. The error message is similar to

**ERROR: Nodal data not found for node ....

As a workaround, define the gluemeshes in sequential order without gaps, i.e.,

GLUEMESH 1 GLUEMESH 2 ...

This bug is fixed in v 8.8.3.


Issue No. 19, posted May 21, 2012

The porthole file cannot be loaded into the AUI when the data fitted concrete material model is used for 2D solid elements in dynamic-explicit analysis.

The error message given is

Error reading ADINA porthole file, expected record 'OUTPUT-2', record label is 'REACFORC'.
The loading of the porthole is stopped.

As a workaround, use dynamic-implicit analysis. This bug is fixed in v. 8.8.3.


Issue No. 18, posted May 21, 2012

Data stored in memory by ADINA is corrupted and the program stops if the op2 result output is requested in an analysis where a shell with many (e.g. more than 20) layers is used and many elements are in the group. ADINA stops and no results are produced.

As a workaround, use more element groups, e.g., by the commands EGCONTROL MAXELG=200 or PPROCESS NPROC=5. This bug is fixed in v. 8.8.3.


Useful Hints and Issues
Regarding the Use of the ADINA System, v. 8.8.1

Issue No. 17, posted May 4, 2012

If multiple prescribed temperatures are applied on a cyclic boundary node, then only the last temperature is taken by the program for that node.

There is no workaround. This bug is fixed in v. 8.8.2.


Issue No. 16, posted May 4, 2012

If prescribed temperatures are applied on a shell mid-surface in an ADINA-TMC heat flow solution, then the program applies temperatures on the top surface only, instead of on the top and bottom surfaces.

There is no workaround. This bug is fixed in v. 8.8.2.


Issue No. 15, posted May 4, 2012

When a model contains many complicated parts, if the FACELINK command is used with OPTION=ALL, the execution of this command is very slow.

As a workaround, set the value of the parameter WARNING to NO (FACELINK OPTION=ALL WARNING=NO). This bug is fixed in v. 8.8.2.


Issue No. 14, posted April 17, 2012

The AUI on 64-bit Windows may crash when loading a huge porthole file with memory allocation of 24 GB or more.

There is no workaround. This bug is fixed in v. 8.8.2.


Issue No. 13, posted April 17, 2012

In certain rare cases, when the time step subdivision resulting from the ATS scheme in ADINA causes the program to skip over the second time step solution, stress/strain results are not output in the op2 file even if they are requested.

There is no workaround. This bug is fixed in v. 8.8.2.


Issue No. 12, posted April 17, 2012

The 3D-Iterative solver does not work properly if 3D bolts are present in a model. As a consequence, more Newton-Raphson iterations are performed. Solution results are not affected, but solution times might be much longer than they should be.

As a workaround, use the sparse solver. This bug is fixed in v. 8.8.2.


Issue No. 11, posted March 27, 2012

If a large number of imposed 3D heat fluxes have different arrival times, and the number is larger than the number of time functions, then the program stops with an error message.

As a workaround, specify dummy time functions so that the number of time functions is greater than the number of 3D heat fluxes with different arrival times. This bug is fixed in v. 8.8.2.


Issue No. 10, posted March 27, 2012

In the AUI, the Show Contact Surfaces icon does not work correctly. The AUI displays an error dialog box when the user clicks this icon.

As a workaround, use the Model Tree to choose the contact surfaces to plot. This bug is fixed in v. 8.8.2.


Useful Hints and Issues
Regarding the Use of the ADINA System, v. 8.8.0

Issue No. 9, posted February 29, 2012

ADINA crashes if the EnSight interface output is requested for 2D contact analysis. No geometry or results are produced.

There is no workaround. This bug is fixed in v. 8.8.1.


Issue No. 8, posted February 29, 2012

When using 3D-bolt elements, it is necessary to assign a different bolt label number to each 3D-bolt element group.

When several 3D-bolt element groups use the same bolt label number, the AUI incorrectly generates a .dat file without an error message. When ADINA runs using this .dat file, ADINA either stops in the equilibrium iterations, or the porthole file cannot be loaded by the AUI.

An additional input error check will be added in v. 8.8.1, so that the AUI cannot generate a .dat file when several 3D-bolt element groups use the same bolt label number.


Issue No. 7, posted February 29, 2012

ADINA crashes when exporting an op2 geometry data block that includes Nastran axisymmetric elements in the global X-Z or X-Y plane. No op2 results and geometry data are produced.

There is no workaround. This bug is fixed in v. 8.8.1.


Issue No. 6, posted February 14, 2012

The ADINA program crashes when 3D-Shell elements are used in the analysis and an EnSight interface output is requested. This is because 3D-Shell elements are not supported in the EnSight interface.

There is no workaround. This bug is fixed in v. 8.8.1.


Issue No. 5, posted February 14, 2012

In the AUI, a transformation of type scale is not created correctly under the following conditions:

  1. Scale factors are not all the same, and
  2. A local coordinate system is used in which the coordinate axes are not aligned with the global coordinate axes.

This bug is present in all previous versions. There is no workaround. It is fixed in v. 8.8.1.


Issue No. 4, posted February 14, 2012

In the AUI, when a nonlinear spring element group with properties in the skew system is defined (command EGROUP SPRING NONLINEAR=MNO-G SKEWSYSTEM=YES), if a data (.dat) file is generated more than once, only the first one is correct. The DOF flag on the second node of the spring elements in the group is set to zero after the first data file is generated. As a consequence of this, when the ADINA solver program loads the data file, it issues an error message and stops.

As a workaround, enter the command EGROUP SPRING NONLINEAR=MNO-G SKEWSYSTEM=YES again each time before generating the data file. This bug is fixed in v. 8.8.1.


Issue No. 3, posted February 14, 2012

In the AUI, mapped (rule based) mesh generation for a primitive body (GBODY MESHING=MAPPED) may fail when the ADINA Modeler is Open Cascade. Crack mesh generation (CRACK-M MESH) may also fail since it relies on body mapped mesh generation.

The workaround is to use Parasolid instead of Open Cascade. This bug is fixed in v. 8.8.1.


Issue No. 2, posted February 14, 2012

If centrifugal and concentrated force loads are applied together with prescribed displacements, then the ADINA program crashes.

As a workaround, in addition to the above loads, apply a zero pressure load. This bug is fixed in v. 8.8.1.


Issue No. 1, posted February 14, 2012
In the AUI, when the user clicks on the button or menu to access the thermoplastic material dialog box, the program gives an error message and quits the command on 64-bit Windows. On the Linux and AIX platforms, the program crashes.

There is no workaround. This bug is fixed in v. 8.8.1.
