I have taken element size of mesh to be 0.002m. I has worked fine for simulating the contour of volume fraction of solid(for the same mesh). What exactly do u mean by converged mesh?. I am reporting the pressure for inlet and the fluid domain.
I tried again using mesh element size of 0.001m. It resulted in a floating point exception.
These are the solution methods i used for the calculation.
These are the error messages.
How do i rectify the error(floating point exception)?
