Descrizione
Crea un vincolo temperatura iniziale per l'analisi termomeccanica.
introduced in 1.0: May also be used to prescribe a temperature field in a static analysis step (to simulate thermal expansion with no need for thermomechanical analysis with temperature boundary condition).
Two cubes with different initial temperatures exchanging heat
Utilizzo
- Cliccare su
o scegliere Modello → Vincoli termici → Vincolo temperatura iniziale dal menu principale. - Inserire un valore iniziale della temperatura per l'analisi.
Limitazioni
Il vincolo applica la temperatura iniziale a tutti i nodi nel modello FEA
Properties
- Datiinitial Temperature: Initial temperature magnitude.
- DatiReferences - introduced in 1.1: Regions to which the initial temperature is applied.
- DatiEnable Final Temperature - introduced in 1.1: Enabled prescribed temperature field in a static analysis step.
- DatiFinal Temperature - introduced in 1.1: Value of a prescribed temperature field in a static analysis step.
Note
- 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
