ADINA Thermal

ADINA Thermal is used to simulate the temperature field of solids and structures. With many capabilities, including 2D/3D steady or transient heat transfer and time and temperature-dependent material properties, even problems involving piezoelectric analysis and freezing and melting conditions can be simulated.

The ADINA Thermal program is used for the solution of heat transfer problems in solids and structures. It has powerful features such as radiation between surfaces of arbitrary geometries, element birth-death options and capabilities for highly nonlinear material behavior.

ADINA Thermal analysis capabilities include:

  • 2D & 3D conduction, convection and radiation
  • Solids and shell structures
  • Steady-state and transient conditions
  • Radiation between arbitrary surfaces
  • Element birth and death options
  • Time and temperature-dependent material properties
  • Electrostatic, seepage and piezo-electric analysis
  • Latent heat effects, e.g., freezing and melting conditions
  • Coupling to ADINA Structures (ADINA TMC)

A unique capability of ADINA Thermal is the analysis of radiation between surfaces. The surfaces can have arbitrary geometries, can be arbitrarily obstructed and radiate upon themselves.

The bottle in this figure was analyzed using this radiation capability.

Welding-induced residual stress analysis requires a reliable nonlinear analysis system with specialized modeling techniques. ADINA Thermal and ADINA Structures are used successfully in welding analysis.

The finite element calculation was performed using the birth/death options of the elements, with material properties highly dependent on temperature.

The solution was obtained using 3 restart runs and 1,500 time steps.
