Text Box: Thermal Analysis

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 behaviour.

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.

 

Thermal analysis for SAW (Submerged Arc Welding), multipass butt weldment. 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.
