Description

Creates an initial temperature constraint for a thermo-mechanical analysis.

Usage

1. There are several ways to invoke the command:
   • Press the FEM ConstraintInitialTemperature button.
   • Select the Model → Thermal Constraints → Constraint initial temperature option from the menu.
2. Enter an initial temperature value for the analysis.

Limitations

The constraint applies the initial temperature to all nodes in the FEA model

Notes

1. The constraint uses the **INITIAL CONDITIONS card in CalculiX. The initial temperature constraint is explained at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node215.html
