Thanks Phelype for your quick reply,
Actually I know how to use corpor.f, I did it ùany times by the pasr, but I'm not realy stisfied by the result. The corpor code have a great advantage to other shemes I've found in the litterature cause the mass balance is fullfilled, however I can't understand why only a portion of the total volume is loaded in the porous medias, this volume corresponds to (n*V), n is the porosity.
My question is about wether is possible to couple a new code for Saint-Venant equations with porosity with the full finite element scheme of Telemeac2D.
