hi,
i have a 3D geometry with 603969 node and 2286163elements in ansys cfx 14.5. its simulation of a tower with two same porous domain. two countercurrent gas and liquid phases flows in it.
when i use :loss model- fluid dependent-isotropic loss- and whether permiability... or inertial loss coefficient... models, it gives MEMERR error at first step.

i try serial , parallel mode on core i7 system, lower and higher number of nodes,expression and constant values for loss coefficients, but again it gives MEMERR error.

First of all: Please do not hijack other threads. I have moved this post to a new thread. In future start a new thread for a new question.

Your question: This error suggests there is something in the porous model which is not defined. It is not actually a memory error, it was just looking for a required parameter and could not find it.
