Hi Rob,

Thank you for the information. Unfortunately, my problem requires two-way coupling so I have to do system coupling simulations. 

I have tried to reduce the time step to a very small value and this negative cell volume still happens, while last step all solutions converge well. Other methods I tried included refining mesh in the corresponding area for the initial mesh. Is there any other method you recommend?

Sincerely,

Eric
