Heat Equation - BodyForce

Post by xfmrman »

I have generated a .step file model of a transformer bushing copper conductor and know the volume, mass, and watts from a current. I am brand new to Elmer. I have reviewed the Heat Equation tutorial and see the same results in Paraview. I am unsure the units for the 'Heat Source' in the "Volume sources" section should be. I am looking for a temperature. I also could have one end of this conductor immersed in a 333K mineral oil bath. When I used the 0.01 input, the temperature is in the thousands of degrees K. Any comments are appreciated. I am unsure if this value is for the surface or the volume?

Review the Elmer's Models Manual for more detailed information such as

Heat Source Real
A heat source h for the heat equation may be given with this keyword. Note that by default the
heating is given per unit mass, not unit volume.
