Default Radiation P1 Model with Spectral Model: Multigray

Dear All,

I have a "converged" solution from a combustion problem (without radiation) and tried to initialise a new calculation including radiation with the P1 model and Multigray as spectral model.

The problem is that the calculation crashes after 2 iterations.

For the initialisation of the radiation (Initialisation -> Radiation Intensity) I put a very small value for the initial radiation intensity.

It semms that this value is not read and the temperature distribution of the converged combustion problem is used instead, which could cause the crash of the linear solver, because of the high combustion temperatues.

Could somebody help me!

Thanks. Andy
