How to model the two phase flow in ALE frame

Please login with a confirmed email address before reporting spam

Hey,

I was trying to study reactive wetting problem using the phase field method along with ALE technique. I artifically give a velocity for ALE moving frame, and let the phase field mode solve the two phase flow in this moving frame. The problem is that if I just give a vertical mesh velocity for moving mesh mode (ALE) the programm runs ok, but when I apply both vertical and horizontal velocity for the moving mesh the code does not converge any more. If you know how to solve my problem, please let know. Your help will be greatly appreciated.

Sincerely,

Shun
