Descrizione
Crea un vincolo FEM per una condizione limite di temperatura.
2D plate subjected to temperature difference
Utilizzo
- Cliccare su
o scegliere Modello → Vincoli termici → Vincolo temperatura dal menu principale. - Selezionare nella vista 3D gli oggetti a cui deve essere applicato il vincolo, che possono essere:
- vertici (angoli)
- bordi
- facce
- Inserire una temperatura da applicare agli oggetti.
Properties
- DatiEnable Amplitude - introduced in 1.1: Enables the use of CalculiX's amplitude for the time variation of the temperature boundary condition. At a given time, magnitude of the boundary condition 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.
- DatiAmplitude Values - introduced in 1.1: Amplitude table in the following format:
time_1, amplitude_value_1 …
- Default is linear increase from 0% at t=0 to 100% at t=1:
0, 0 1, 1
Note
- Il vincolo di temperatura utilizza la *BOUNDARY card in CalculiX. Il vincolo di temperatura è spiegato in http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node163.html
