Problems in thermal co-simulation in CST

Hi all,

I did simulate simple microstrip model to monitor temperature of subtrate and stripline. This work is attached on my post. When I run thermal simulation, this has a following error.

This solver setup would lead to zero fields.Thermal solver stops.

Other microstrip/planar models I did well but only this work has the problem. Could you look at and let me know some points?

Thanks,

Dav-

From the file you attached, it is only a circuit model, you'd better simulate in the MWS.
