Re: Non-physical pressure difference in an annular porous media zone (Pipe Flow)

Thank you for your suggestion.

The figure below shows the 3D pressure results for my pipe. The annular porous region I defined is located at a certain distance from both the inlet and outlet (the area covered by the blue brackets in the figure).

The high-pressure zone is not near the inlet or ...

Re: Non-physical pressure difference in an annular porous media zone (Pipe Flow)

Hello,

Thank you for your reply. I will provide more relevant information. The version of Saturne I used is 8.0.1. The mesh is hexahedral, and the turbulence model is RANS k-ε. The computational domain consists of a circular pipe containing three layers of annular porous media. Below are ...

Non-physical pressure difference in an annular porous media zone (Pipe Flow)

Hi everyone,
I am currently simulating flow through a circular pipe where an annular porous zone is implemented along the interior wall.
I have defined the physical properties of the porous region using the following formulas:

Re: Problem of MPI?

Hello!

I met the same problem with you these days.The case only can be run with one process and when I set the process number more than one the same error ouccers like:

Parallel code_saturne on 10 processes.
