Descriere
Creează o constrângerea de temperatură inițială pentru o analiză thermo-mechanical .
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
Utilizare
- Click pe
or choose Model → Thermal Constraints → Constraint initial temperature from the top menu. - Introduceți o valoarea pentru temperatura inițială pentru analiză.
Limite
The constraint applies the initial temperature to all nodes in the FEA model
Properties
- Dateinitial Temperature: Initial temperature magnitude.
- DateReferences - introduced in 1.1: Regions to which the initial temperature is applied.
- DateEnable Final Temperature - introduced in 1.1: Enabled prescribed temperature field in a static analysis step.
- DateFinal Temperature - introduced in 1.1: Value of a prescribed temperature field in a static analysis step.
Notă
- Constrângerea utilizează **INITIAL CONDITIONS card in CalculiX. Constrângerea inițială a temperaturii este explicat la http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node215.html
