Magnetic field and Thermal study Combined

Hi,

I am currently simulating a model (magentic field study) to evaluate the heat source distribution surrounding an copper inductor cavity and wanted to consider these heat sources asinput for my thermal model .

There is no problem in magnetic field study , can see the surface loss density plot (mf.Qsrh) but when i assign this mf.Qsrh value in thermal model as assigned heat flux I am getting some errors while comuting thermal study ,

1. I can see same intial temperature at all time steps
2. If not the above error (1) , getting error as undefined variable on boundaries (boundaries where heat flux is assigned)

I am attaching my model here , kindly let me know what is the nature of this error.

P.S - I have also included a PID study in this , however dont feel PID is reason for this error . Correct me if I am wrong
