Model Description: I am simulating power dissipation in a 3D chip with RF and DC electrodes embedded beneath insulating layers. The simulation uses:

• Electrostatics (FEM) coupled with Heat Transfer in Solids.
• Stationary study (time-independent analysis).
• Applied Voltage: 100 V on the RF electrodes.

Key Assumption: Since the electrode dimensions are in millimeters (mm), I approximated the 20 MHz RF signal as a DC field (quasi-static assumption) and opted for electrostatics.

Error Message:(below)

Failed to find solution. In temperature: Divergence of the linear iterations. Returned solution is not converged. Not all parameter steps returned.

Does anyone know the any solutions/suggestions??
