Geometric boundary splitting on PLOT3D mesh
I'm a newbye of Fluent. Usually I use CFD++ of Metacomp at my college CFD lab. Now they change the package with Fluent and i'm in tilt :confused:.
The problem is the following:i can write the mesh file (2D STRUCTURED) only in PLOT3D format with my pre-processor and i inmport it in Fluent successfully.
But i don't know how to split a generic boundary in two o more part.
For example: i have a 2d structured mesh, body-fitted on a NACA airfoil (like the type D); the boundary is only one and i have to split it in external region, connection region and the airfoil (entering the number of face-cell and their i-j) position.
How can i make it?
I don't think, that this is possible in Fluent. As far as I know, you cannot split faces in Fluent. Maybe, you can use iso-surfaces....
I had some similar problem once... an I had go back to the geometry generation to do so (http://www.cfd-online.com/Forums/flu...-new-mesh.html).
So, that is the thing i would suggest: Import your mesh to gambit, there you can do all the necessary face split commands and BC definitions.
But I guess, you might lose you mesh when adding new vertices...
Thank you, Ralph.
Now I'll try with Gambit.
