Description
Defines a temperature boundary condition or, optionally, a concentrated heat flux load.
Usage
- There are several ways to invoke the command:
- Press the
Temperature boundary condition button.
- Select the Model → Thermal boundary conditions and loads →
Temperature boundary condition option from the menu.
- Press the
- Press the Add button.
- In the 3D view select the objects the boundary condition should be applied to, which can be vertices, edges, or faces. Optionally, press the Remove button and click on the objects that you want to remove from the selection.
- Choose the constraint type and specify its parameter:
- Temperature (default) - temperature boundary condition, enter the Temperature (K)
- CFlux - concentrated heat flux load, enter the Concentrated heat flux (mW) - this value will be divided by the number of nodes on the underlying geometrical entity to achieve a total flux of a given magnitude on that entity
Notes
- The temperature boundary condition uses the *BOUNDARY card in CalculiX.
- The Concentrated heat flux option uses the *CFLUX card in CalculiX.
