How to solve a Poisson's equation in the beginning of each time step
 
Hi all.

I need to solve a Poisson's equation with determined coefficients before the solution iterations in the beginning of each time step and then some parameter outputs is to be assigned as the input for main equations (U,V,...).
Is that possible in Ansys Fluent?

Thanks for any attentions.
