Hello ,

I use Comsol Script to represent the flow in a cell of soil.

I start with a simple case, a rectangle. 2 segments have a Hydraulic charge and the 2 others have Zero Flux/symmetry

When I aspect to have a zero flux on boundaries, in postprocessing i didn't have a zero value.
How it is possible to fix the value at zero in this case to have a good accuracy on my flux.


Merci
