Excuse me all:
I would like to simulate the gas separation by hollow fiber. the inlet gas is form outside of the fiber, and the permeate goes out in inside of the fiber. the figure attached illustrates the structure of the process.

I drew three model and meshed them. after that imported them in cfx-pre. connected shell(outside of membrane hollow fiber as feed gas), membrane(porous hollow fiber) and inner(inside the membrane as permeate gas) by interface.

In the porouse media(hollow fiber membrane), i applied directional loss in cylindrical components(axial component is 0, radial 1, theta 0). inlet boundary is velocity of 2m/s and outlet is static pressure 0 pa.

However, after exit cfx-per, i am not able to go through the cfx-solver. the message form the solver is listed below:

This run of the ANSYS CFX Solver has finished.

Since i am not quite familiar with CFX, i DON'T know what is the reason for the failure of solving and how to correct the error.

Is there any one who can help me?

many thanks in advance.
