Hi Everyone,
I am new to Ansys- CFX and am trying to simulate a rectangular porous domain (porous membrane) as described in the image. The dimensions of the rectangular body are 1000 mm (length) x 20 mm (height) x 0.0001 mm (thickness). I am getting the above said error as soon as i start the solution. Please help me with this.

Have a look at the Output file (*.out). It usually contains messages before the crash which might give an indication of what is going wrong.

Hi Vigneshwaran

Solver returns with error code-1 if there is an issue with the def file.
First- Check the mesh input units (cm,mm,in)
Make sure the setup is setup properly.
The out file mentions an error on Re No. Do cross check that too.

Cheers!

This is the important part of your out file:
