Volume Heat Flux

The volume heat flux boundary condition acts like a volumetric heat source. This type of boundary condition is used for analysis types involving heat transfer. The figure below shows the necessary input parameters:

Users should define the volumetric Heatflux value, in units of \([W/m³]\) or \([\frac {Btu}{s.in^3}]\). The resulting heat flux will depend on the volume of the assignment.

Besides a fixed value, it is also possible to use tables and formulas to input the heat flux.

Important

The heat flux can be positive or negative. For a positive input, heat goes into the domain.
For a negative value, heat is removed from the volume.
