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.
- In the 3D view select the objects the boundary condition should be applied to, which can be a vertices (corners), edges, or faces.
- Enter a temperature to apply to the objects.
Option
By default, this feature defines a temperature boundary condition. By using the option Concentrated heat flux, one can specify a heat flux value (in mW) in each node belonging to the selected geometrical entity.
Notes
- The temperature boundary condition uses the *BOUNDARY card in CalculiX. It is explained at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node163.html
- The Concentrated heat flux option uses the *CFLUX card in CalculiX: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node168.html
