I am working on the "PMSM with Thermal Model" example of MATLAB but when i put the MOSFET in this problem i am getting the errors

For the motor model, i have taken from the thermal PMSM model from MATLAB examples. when i put the MOSFET for switching i am getting this error. I want to put the MOSFET for the swithing for my MODEL.

An error occurred while running the simulation and the simulation was terminated

Caused by:

• ['ee_motor_pmsm_thermal/Solver Configuration']: At time 0.000550, one or more assertions are triggered. See causes for specific information.
• In divide, the denominator must be nonzero. The assertion comes from: Block path: ee_motor_pmsm_thermal/FEM-Parameterized PMSMAssert location: o (location information is protected)
