interFoam solver - Vacuum

saba_saeb · June 26, 2012, 16:19

Hi,

I have used interFoam solver and followed damBreak example to simulate a multi-phase flow and I succeeded.
Now, I want to change the condition in such a way that one of the fluids is replaced by vacuum (water droplet falling in vacuum). What changes should I implement or which boundary conditions suit my problem well? Any suggestion would be much appreciated.

Hi Saba, I am also having the same issue using the interFoam solver and trying to simulate vacuum in a casting process. Does anybody have suggestions about it?

Thank you!

Does it make sense to use a continuum method to model a vacuum?

Hi Anton,

maybe not. But how to tell Openfoam that vacuum cells are EMPTY?
What would be your approach?

Best Regards
