porous jump
 

Hi everyone,

Im a new user of fluent and I am trying to model a 2d pipe leakage. The pipe is situated into sand and above (and below) the sand there is plain soil. I have used GAMBIT to produce the grid and defined tha boundary condition of the line separating the two materials as porous jump. When I try to read the mesh file in FLUENT i get the error message: "Cannot change porous_jump to porous-jump because there is only one adjacent cell thread."

Any ideas on what I need to change?

Thanks a lot, Louisa

Re: porous jump
 

"only one adjacent cell thread" This means fluid cells are only defined on one side of this BC ... a nonsensical situation.

Re: porous jump
 

This error means that u r applying porous jump BC on extreme boundary..on the other side of porous jump there is nothing..actually porous jump can be applied on a face which connects two media..one side u have fliud flow nd other side some porous media like sand. then it will work regards nitin
