Internal heat source PDE

Dear community,

I am using the PDE toolbox to study the release of latent heat from a solid geometry. To do so, I need to set the internalheatsource in the thermal model. Is this energy per unit volume [J/m3] or power per unit volume [W/m3]?

In general, is there any place where the units of measure used in the toolbox are clearly declared?

Thank you,

The unit of heatSourceValue in internalHeatSource is W/m3. You can refer Page No. 5-214 of Partial Differential Equation User’s Guide for more information.
