ADINA 9.2.4 has been released.

These Useful Hints and Issues, while reported for the specific version 9.2.4, are usually also applicable to the ADINA versions 9.2.3, 9.2.2, 9.2.1 and 9.2.0.

Useful Hints and Issues
Regarding the Use of the ADINA System, v. 9.2.3

Issue No. 32, posted Sep 28, 2016

In the AUI, pressure loading is wrong when it is applied on a geometry face meshed with 3D plane stress elements and the load references a surface spatial function.

There is no workaround. This bug is fixed in v. 9.2.4.

Issue No. 31, posted Sep 28, 2016

The AUI crashes when UNDO is applied after loading an IGES file in ADINA-M/OC.

There is no workaround. This bug is fixed in v. 9.2.4.

Issue No. 30, posted Sep 28, 2016

In ADINA Structures, restart file information is not printed correctly and restart time checking is also incorrect if:

1) Saving for a certain number of steps is requested on the restart file and
2) The total number of steps is not divisible by the requested number of steps.

As a result, the program gives an error when the restart file is used in a restart run.

As a workaround, save all time steps in the restart file or make sure that the total number of steps is divisible by the number of saved steps. This bug is fixed in v. 9.2.5.

Issue No. 29, posted Sep 28, 2016

The porthole file cannot be loaded for ANALYSIS MODAL-PARTICIPATION-FACTORS if a static correction is not specified.

As a workaround, use ANALYSIS MODAL-PARTICIPATION-FACTORS CORRECTION=YES. This bug is fixed in v. 9.2.4.

Issue No. 28, posted Sep 28, 2016

For nonlinear damping, i.e., if the damping matrix is updated every step, and if the Bathe method is used, the initial damping matrix is taken for the second substep.

There is no workaround. This bug is fixed in v. 9.2.4.

 

Useful Hints and Issues
Regarding the Use of the ADINA System, v. 9.2.2

Issue No. 27, posted July 14, 2016

ADINA crashes if the Noh-Bathe method is used with prescribed velocities in a restart run in which time span of the restart run is smaller than that of the first run.

There is no workaround. This bug is fixed in v. 9.2.3.

Issue No. 26, posted July 14, 2016

Concentrated masses applied on constrained rotational DOFs are not included in reaction calculations, therefore the reactions are incorrect in such cases.

There is no workaround. This bug is fixed in v. 9.2.3.

Issue No. 25, posted July 14, 2016

In ADINA TFSI analysis, if different FSI boundaries in the CFD model are connected, and temperature coupling is handled through the boundaries, the temperature solution is inaccurate along the connected FSI boundaries. Note that the AUI issues a warning message when different FSI boundaries are connected.

The workaround is to ensure that different (i.e., not the same, but possibly connected) FSI boundaries are not connected. To do this, the user can group different FSI boundaries which are connected into one FSI boundary. This bug is fixed in v. 9.3.

Issue No. 24, posted July 14, 2016

This bug is triggered under the following conditions:

1) The analysis zooming feature is used in ADINA Structures, and
2) A porthole file from the global model (without zooming) is already opened in the AUI.

Then the porthole file from the zoomed model cannot be opened in the AUI using either the restart or the append option.  The AUI gives an internal error message.

As a workaround, open the porthole file from the zoomed model in a separate AUI run. This bug is fixed in v. 9.2.3.

Issue No. 23, posted July 14, 2016

Due to a bug in the AUI, porthole files with the following data cannot be opened:

1) ADINA Thermal analysis, and
2) Radiosity elements are in the the model, and
3) The birth-death feature is used in the radiosity elements, and
4) The results from the radiosity elements are not written to the porthole file.

The AUI gives an internal error message.

As a workaround, save the results from the radiosity elements to the porthole file. This bug is fixed in v. 9.2.3.

Issue No. 22, posted July 14, 2016

The AUI can crash under the following circumstances:

1) The AUI is opening a file, such as a porthole or database file, and
2) The AUI cannot open the file, for example, because the file does not exist, and
3) The filename is longer than 80 characters.

The crash occurs only when the AUI cannot open the file.

Therefore a workaround is to specify a filename that the AUI can open, for example, to specify a filename
corresponding to a valid porthole or database file. This bug is fixed in v. 9.2.3.

Issue No. 21, posted June 15, 2016

A Parasolid model that has a conical surface represented by one single face cannot be loaded into the AUI.

As a workaround, split any conical surface into two faces before exporting or saving the Parasolid file from the third party program. This bug is fixed in v. 9.2.3.

Issue No. 20, posted June 15, 2016

This bug involves the following conditions:

1) Band plots of modal results, for example band plots of modal stresses, and
2) User-specified mode shape factor entered, for example, using the RESULTCONTROL command, and
3) Animations, for example, using the Movie Mode Shape icon.

Under these conditions, the user-specified mode shape factor is not used during the animations. Therefore the scaling of the band plots will not be correct in the animations.

As a workaround, do not specify a mode shape factor in the RESULTCONTROL command. This bug is fixed in v. 9.2.3.

Issue No. 19, posted June 15, 2016

This bug involves the following conditions:

1) ADINA-TMC analysis using heat transfer only, and
2) MESHINTEGRATION command used to integrate or average the results on a cutting surface

Under these conditions, the option MESHINTEGRATION CONFIGURATION=DEFORMED must be used to obtain the integrated or averaged results.  If the default MESHINTEGRATION CONFIGURATION=ORIGINAL is used, then no results are obtained.

As a workaround, use the option MESHINTEGRATION CONFIGURATION=DEFORMED. This bug is fixed in v. 9.2.3.



Useful Hints and Issues
Regarding the Use of the ADINA System, v. 9.2.1

Issue No. 18, posted May 5, 2016

For some models made with ADINA-M/OCC (Open Cascade geometric modeler), when boundary layer meshing is involved, the command to mesh bodies (GBODY in command mode) fails without any error message.

There is no workaround. This bug is fixed in v. 9.2.2.

Issue No. 17, posted May 5, 2016

A loading porthole error occurs in the AUI when the model contains MNO-G type spring elements and RESULTS=STRESSES output is requested. The results are good but cannot be displayed for post-processing.

If RESULTS=FORCES (the default) is chosen instead in the output, the results can be loaded and displayed without any error. This bug is fixed in v. 9.2.2.

Issue No. 16, posted May 5, 2016

When restarting from static to dynamic analysis and the 3D-iterative solver is used in the restart run, if initial velocities are specified at restart, the program might crash.

As a workaround, use the sparse solver if initial velocities are specified when restarting from static to dynamic analysis. This bug is fixed in v. 9.2.2.

Issue No. 15, posted May 5, 2016

The contact search determines, for each contactor node, the target segment with which that contactor node interacts. When the target surface consists of highly distorted segments, it is possible for the contact search to not find the target segment for contact, even when the contactor node is in contact with the target.  When this happens, convergence is difficult, and the contact at that node is in error.

As a workaround, make sure that the target surface mesh does not contain highly distorted segments. This bug is fixed in v. 9.2.2.

Issue No. 14, posted May 5, 2016

When the mesh plot contains highly distorted 3D brick elements, and the Model Outline icon is used to plot just the outline of the model, sometimes extra lines are also plotted.

There is no workaround. This bug is fixed in v. 9.2.2.

Issue No. 13, posted May 5, 2016

When an existing section line is modified, if one of the end points is also an end point of its parent line, an internal error occurs.

There is no workaround. This bug is fixed in v. 9.2.2.

Issue No. 12, posted May 5, 2016

The Arrhenius shift calculation in the viscoelastic material model does not give accurate results when very large decay coefficients are input in the Prony series table and the solution time is long.

There is no workaround. This bug is fixed in v. 9.2.2.

Useful Hints and Issues
Regarding the Use of the ADINA System, v. 9.2.1

Issue No. 11, posted April 4, 2016

If thermo-mechanical coupling (TMC) analysis is used with the shell large displacement (TL) formulation, and a request is made to save director vectors in the porthole file, the porthole file cannot be loaded into AUI.

There is no workaround. This bug is fixed in v 9.2.2.

Issue No. 10, posted April 4, 2016

If mode superposition is used with prescribed displacements, and constraint equations are present in the model, the porthole file cannot be loaded into the AUI.

There is no workaround. This bug is fixed in v 9.2.2.

Issue No. 9, posted April 4, 2016

This bug involves plotting of a single layer of multilayered shells. It should be possible to plot the entire layer in a user-specified color using the COLORZONE command, but, due to the bug, the entire layer is plotted in the default color.

As a workaround, define a zone of just some of the elements in the layer. The color of this zone can be set using the COLORZONE command. This bug is fixed in v 9.2.2.

Issue No. 8, posted April 4, 2016

This bug involves plotting of elements of multilayered shells.  Suppose that there are several orthotropic layers in the multilayered shell, and that not all of these orthotropic layers have the same material axis directions.  There is no way to plot the material axes of just one of the orthotropic layers, even if the plotted zone contains just one orthotropic layer.  Instead, the material axes of all of the layers are plotted.

There is no workaround. This bug is fixed in v 9.2.2.

Issue No. 7, posted April 4, 2016

In ADINA Structures contact analysis, if a contactor node is constrained in such a way that the number of independent degrees of freedom at the node to which the contactor node is constrained is greater than 3, the program might crash with a sparse solver internal error. An example is if the contactor node is the slave node of a rigid link, and all six master degrees of freedom of the rigid link are active.

As a workaround, make sure that the number of independent degrees of freedom for each constrained contactor node is less than or equal to 3. This bug is fixed in v 9.2.2.



Useful Hints and Issues
Regarding the Use of the ADINA System, v. 9.2.0

Issue No. 6, posted March 9, 2016

During post-processing, if a zone of the solid model in an FSI problem is displayed after creating a particle trace plot, an internal error occurs. This happens when the porthole file of the solid model is loaded after the particle trace plot is created, and then the solid zone is displayed.

There is no workaround. This bug is fixed in v 9.2.1.

Issue No. 5, posted March 9, 2016

In the Windows version, when an idb file is saved in a folder with a space in its name (e.g., "C:\temp\first folder") and the file is moved to another folder without its associated Parasolid (.x_t) file, the following error occurs when opening the idb file:

Unable to retrieve Parasolid part: (filename)
As a workaround, move the Parasolid file to the same folder as the idb file. This bug is fixed in v 9.2.1.

Issue No. 4, posted March 9, 2016

In the Windows version, when an idb file is saved in a folder with no space in its name and the file is moved to another folder with space in its name (e.g. "C:\temp\second folder"), the following error occurs when opening the idb file:

Cannot delete file ....\(filename)_tmp
There is no workaround. This bug is fixed in v 9.2.1.

Issue No. 3, posted March 9, 2016

The ADINA program stops with an error message if the zooming option is used with the TMC option in a restart run from static to dynamic analysis.

There is no workaround. This bug is fixed in v 9.2.1.

Issue No. 2, posted March 9, 2016

The op2 result of a model with the 1-node 6-DOF spring element cannot be loaded into NX for post-processing.

There is no workaround. This bug is fixed in v 9.2.1.

Issue No. 1, posted March 9, 2016

In explicit analysis using 2D solid elements with the orthotropic material model, when stresses are printed or saved in the material coordinate system, the stress values are incorrect. All other results are correct, including displacements, velocities, forces, etc.

As a workaround, print or save the stresses in the global system. This bug is fixed in v 9.2.1.
