3-phase flow - compressibleMultiphaseInterFoam

eca · January 21, 2019, 17:18

Hello everybody,

I'm trying to solve 3-phase flow within a horizontal pipe with vertical pipe connection which has dead end. I want to start with the geometry consisting pure air, and then water and oil are coming from the inlet. How is the BCs and setFieldsDict supposed to be? I tried some different cases but every time I got different error messages such as maximum iteration number exceeded or floating point... Could you please share me your opinions and suggestions?

Thank you in advanced.

Hello Eca,
in case this is still up-to-date:
I had a similar question and just found this:
multiphaseInterFoam vs multiphaseEulerFoam

As for set fields you can set air as default (1 in defaultFieldValues). You do not need to set boxes for the inlet, it is defined in 0/alpha.*.
