Unable to make one mesh a heat source when using more than one mesh in simulation

Hello,

I am having an issue with setting up one of my meshes as a heat source.

In my simulation I have two different meshes however I only want one mesh to be a heat source.
I assigned a constant temperature of 400 to cad2 as shown below but I get a nasty looking error message with this (copied to bottom of post)

fix cad1 all mesh/surface/stress file spmesh.stl type 1 scale 0.1 rotate axis 1 0 0 angle 0 move -0 -0 -0 curvature 1e-5 wear finnie
fix cad2 all mesh/surface/stress file sp1mesh.stl type 1 scale 0.1 rotate axis 1 0 0 angle 0 move -0 -0 -0 temperature 400 curvature 1e-5 wear finnie

I noticed when I assigned both meshes cad1 and cad2 a constant temperature it was able to run perfectly fine but I need only one mesh to have a constant temperature.

Is there a way of working around this? Any feedback greatly appreciated.

Regards,
Jonathan
