Descriere
Creează o constrângerea de temperatură inițială pentru o analiză thermo-mechanical .
introduced in 1.1: 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
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.
- DateEnable Amplitude - introduced in 1.1: Enables the use of CalculiX's amplitude for time variation of the prescribed temperature field. At a given time, magnitude of the field is multiplied by the amplitude value corresponding to that time. Linear interpolation is used between the specified values. Constant values are used outside of the specified range.
- DateAmplitude Values - introduced in 1.1: Amplitude table in the following format:
time_1, amplitude_value_1 …
