Hi,

I try solve thermal plasma model but get this

Failed to find consistent initial values.
Last time step is not converged.

Thank for your help.

For a nonlinear iterative solution, one must enter initial conditions reasonably close to the final solution in order to expect convergence to occur. Also, try relaxing some of the damping to allow for slower convergence.
