I am trying to simulate an electric arc in a flowing gas through a nozzle. as you can see in the attached model, the arc heat is been added as a heat source in the hmnf interface. also i created a ramp parameter to sweep the heat source value in the auxiliary sweep.
Now , as the ramp value goes higher , the solver gives the following error :
Failed to find a solution for all parameters,
even when using the minimum parameter step.
In Segregated Step 2:
Segregated iteration leads to undefined function value.
There was an error message from the linear solver.
The relative residual (1.2e+003) is greater than the relative tolerance.
Returned solution is not converged.
I tried different type of meshes , ramping the materiel properties and it didn't work out.
it would be great if any could help me solve this problem.
Best Regards ;
