I´m trying to simulate multiphase simulation with phase change between water and water vapour with Particle Model.

I have already updated the expert parameter but I still go this message, does anyone knows the source of the problem?

You should consider the information the message is saying. It is saying that the temperatures have been clipped. So did your temperature field start to diverge? Or a simulation setup error means the temperature is not controlled properly somewhere? Is it adequately converged? Have you modified the temperature clipping settings?

When I remove turbulence and viscous work from my fluid pair the error message dissapears.

I´m using H20l and H20v as my simulation material, do you think it´s related to the table generation values (max and min temperature and pressure)?

The conditions you are modelling are too complicated. Did you consider moderate conditions as a start and then speed things up? That would be a useful approach.


BTW, why on earth should you switch on viscous work? I think this is completely irrelvant.
