solidification problem

Karthik

Dear friends,

I am dealing with a solidification problem, where indial test case is run with a closed domain without any outlet, considering the flow to be compressible.

I am solving this problem as a multiphase problem .I press the mould through the inlet which is considered incompressible. Already i have air present inside which i consider it as a compressible.

Is it possible to model this case as a hybrid ( both compressible and incompressible)?

As of now, i dont take any temperature effects into consideration. I am trying to analyse the flow nature with pressure distributions.

Or i should take the case of solving it as a compressible flow problem?

Kindly clarify

Thanks in advance
