Hi,
You can indeed control the gradient and the mean pressure independently in a
flow problem.
The problem is in the coupling. If crack aperture (or deformation) depends on

Thank you Jerome for your input. As I said, I struggle a little bit with
the periodic boundaries concept.

Hi all,
I am still a bit confused with the periodic boundaries and I am wondering if
there is a way to impose a pressure gradient with gradP such that the average
pressure in the cell is not equal to 0?
