Dear Birger,
sorry for the late reply, but I was quite busy this week.
I am not sure about the velocities, but you can at least get the
gradient quite easily with the box discretization using:
auto elemSol = elementSolution<Element, ElementVolumeVariables,
FVElementGeometry>(element, elemVolVars, fvGeometry);
const auto gradP = evalGradients(element,
element.geometry(),
this->fvGridGeometry(),
elemSol,
scv.center())[pressureIdx];
With the gradient, you should be able to recalculate your velocity
(magnitude).
I hope that helps, best regards
Johannes

Dear all,
is there any quick solution to access the phase (Darcy) velocities
within the source method of the problem class?
I only need the magnitude (not the direction) to calculate bacteria
attachment/detachment terms. I am using an extended 2pnc model and the
box discretization.
Thank you in advance.
Regards Birger
