MHD and existing flow field
 

Hi,

I would like to just solve the "electrical potential" for a existing flow field (which is already solved by fluent before). There is no magnetic force, so there is no added force term to navier-stokes. So, I don't need to solve flow field again.

Is there any way that I can solve the electrical potential without solving the flow field again?

Thanks.

PS: I know I can run few more iterations and get the solved solution for both flow field and electrical potential field. But for some reasons, I have to keep the solved (converged) flow field untouched.

I found the solution. For future inquiries:

go to "Solution controls" --> Equations --> check/uncheck desired equations
