Power inverter in Q3D - need to optimize the layout

Hi!
I am trying to develop a power inverter. But first , I need to optimize the layout in terms of resistance, inductance and current crowding. I am working with Q3D (though I am not sure if this the right tool). I will be using SiC JFET dies for the switches. In the material selection guide, SiC does not exist. But for the values of conductivity that I feed in for SiC, the software assumes it to be an insulator and excludes it from the conduction net. Is there a way to get around this?

Can u please help me ....Is it possible to simulate the circuit with SiCJFETS in any software especially in PSIM...Did u try simulation
The bulk resistivity of SiC can really be variable depending on the fabrication process. But a reasonable assumption would be values of 1e4 to 1e8 ohm-cm. It's a pretty isolating substrate anyway...
