Default Gridgen and Fluent
Posts: n/a

Any suggestions on why FLUENT is not reading the case file properly produced by Gridgen? Hanging cells and node error, something like this. It is a 2D mesh - I have double checked everything and it looks fine, however I dont understand the behaviour this time!

Any advice is greatly appreciated.

Thank in advance.

you have to reverse 2d block (face) orientation under the block menu and export again. it's long time i have not used gridgen so i dont remember exact command but you can find.

Well, I am in the 2D block section of the FLUENT data export analysis. I tried using a simple extruded mesh with just one face an it worked, however this one is a combination of many 2D faces and they all lie on the xy plane.

Fluent gives Grid Error - You can see all the boundary conditions it reads in but after a while it complains about some partial mesh on a plane or something!

Any ways thanks for the suggestion - If you can think of something else than please let me know.
