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.
