Unhappy Transient ICP in CFD-ACE+

creten is on a distinguished road
Hi everyone,

I was wondering if anyone had ever successfully modeled a transient plasma simulation in CFD-ACE+ with both an RF coil current and an RF voltage source. I have been trying to run one of these with the Flow, Heat, Chem, Plasma, Electric and Magnetic modules activated and the simulation works fine when I deactivate the coil current. When the coil current is activated, the gas temperature blows up (goes to over 10000 K) and I obviously get divergence. The RF is at 40.68 MHz, so shouldn't be too high. The aim is to add in a DC magnetic field as well so that I can see the effect of a solenoidal B field, hence why I can't just run a steady state ICP (magnetic effect on electron transport are only activated in CCP transient mode).

If anyone has any experience in this area, I'd love to hear from you!
