Описание

Defines an initial temperature for a thermo-mechanical analysis.

Применение

1. There are several ways to invoke the command:
   • Press the Initial temperature button.
   • Select the Model → Thermal boundary conditions and loads → Initial temperature option from the menu.
2. Enter an initial temperature value for the analysis.

Ограничения

This tool applies the initial temperature to all nodes in the FEA model - it's not possible to select individual regions.

Примечания

• This tool uses the *INITIAL CONDITIONS card in CalculiX. It is explained at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node215.html
• Initial temperature has to be defined for all thermomechanical analyses performed with CalculiX, even the steady-state ones.
