reversing faces

April 30, 2007, 14:26

Hi, I'm using the fluent parallel solver on a dual core computer. Importing a 3D mesh I have the following warning message: "Warning: Reversing 30876 faces, zone 4." If I read the same mesh in the serial solver there is no such a warning, but I cannot run the simulation because of memory requirements. What that message means and how to fix it? thanks

try reading the mesh and write the case in "serial" and read the "case" not mesh in parallel.

that was wonderful bashu!!! but i have a question: what problem occure if there is such a warning? I am simulating a 2D reactor impeller and have such a warning in my simulation.

It could be because of mesh not been done somewhere... In my case, it was giving same problem - 'reversing faces ....' while reading mesh. But later I found mesh hadn't been done. When I did meshing again, it worked in parallel also.

I don't understand what you mean by "mesh had not been done". Can you please explain? Do you mean that the mesh was not read properly? or that it was not exported into fluent format?
