Hello,

I have only one question. How is it possible that interFoam can reproduce the capillary action in a thin tube while multiphaseEulerFoam does not? Water column goes down for the mEF solver!

It is very simple to modify the tutorial case in OpenFoam for the latter solver.

Thanks for answers.

Hi Majkl,

Interfoam and eulerfoam(twophaseEulerFoam or multiphaseeulerfoam) is suitable for different cases. for this interfoam tutorial, surface tension play an important role. but in two-fluid model, it is not.

for example, if u initialize a rectangle bubble in interfoam case, it will get round. but if u erase the surface tension term in the code of interfoam. it will keep to be rectangle always. also in interfoam, wall contact angle plays a role.

eulerfoam is not suitable to surface tracking. for more information I recommend Rusche's phd thesis.

best,
