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)

Use

  1. Click on or choose FEM Constraint heatflux from the top menu.
  2. Select in the 3D-view the surface(s) the constraint should be applied to.
  3. Enter the desired surface temperature, film coefficient and environment temperature.

Limitations

Notes

  1. 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
