Descrizione

Crea un vincolo temperatura iniziale per l'analisi termomeccanica.

Utilizzo

1. Cliccare su o scegliere Modello → Vincoli termici → Vincolo temperatura iniziale dal menu principale.
2. Inserire un valore iniziale della temperatura per l'analisi.

Limitazioni

Il vincolo applica la temperatura iniziale a tutti i nodi nel modello FEA

Note

1. Il vincolo usa la **INITIAL CONDITIONS card in CalculiX. Il vincolo temperatura iniziale è spiegato in http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node215.html
