Hello,

I am trying to model a contact angle change by maxwell stress tensor using the moving mesh module coupled with the electrostatic (from where the electric field is calculated).

The modules work fine taken separately, but when coupled with the body force, or even without coupling but solved at the same time, the contact angle doesn't change, in fact the system doesn't converge.


Can you tell me if there is any problem in this coupling?

Hi Vito
I am working on the same problem. Actually I used Level Set function and it worked OK, but thickness of interface was an issue. So, I am now starting using moving mesh, but having some problems in the flow.
We can exchange experience. You can email me on aseissa@gmail.com
Thanks
Ahmed

Hi guys ,
I have the same problem, there is no gravity as a default body force in Two phase flow moving mesh ?
