Default porous medium
Posts: n/a
Hi all,

My 2 cases have the same model and boundary conditions but different number of meshes.I tried to translate the global coordinate system of the 1st case to the new one using VTRANS.It worked properly and the simulation can be run.

When I did the same processes with the 2nd case,the problem is occurred during running the simulation because the solution became infinity at the first iteration.So I tried to deactivate the porous cells to be normal cells,then everything is fine.I guess the problem must be occurred by porous medium..

These are the steps that I used to process my cases. -vtrans,1,vset -changed the gravity direction -change the velocity to new component -change coordiante system of porous medium

*** every setting values of both cases are the same and 2 cases can also run the simulations reasonably before changing coor. system ***

Does anyone know how to solve this ,please suggest me ...Thanks a lot..
