Description
This constraint specifies film heat transfer of a surface at temperature T and with a film coefficient h to the environment or sink at temperature T0 . The convective heat flux q will satisfy: q = h(T -T0)
Usage
- There are several ways to invoke the command:
- Press the FEM ConstraintHeatflux button.
- Select the Model → Thermal Constraints → Constraint heatflux option from the menu.
- In the 3D view select the face(s) the constraint should be applied to.
- Enter the desired surface temperature, film coefficient and environment temperature.
Notes
- The constraint uses the *FILM card in CalculiX. The heatflux constraint is explained at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node203.html
