Ideal gas law – Solver/basic tips

      Hi all,

      I have a radiation model via Monte Carlo wherein I am injecting energy into a weld joint of two metals, and I am interested in the pressure increase via radiation of the Air Cavity as energy is further injected via radiation. I set up the air as "ideal-gas" instead of constant density.

      Density-based solver is suitable for high number Mach flows (supersonic or hypersonic). If this is not the case, use pressure-based solver.
      In regards to convergence issues, I would suggest to check mesh quality and start with a simpler problem without radiation. Just apply some kind of temperature boundary condition to see what is going on. The reason of divergence could be in different parts of the model and it is interesting to start with simpler cases.
