Fluent, Grid Builing Issue
Hi,
I'm trying to model the flow around around a wing mirror. I've taken the geometry in gambit, created a volume around it and subtracted the mirror geometry from it. I then mesh it and export the mesh for use in Fluent. When i read the mesh in Fluent i get an error stating "Building... grid, Cell Centroid is xc 3815.967859 yc -975.544274 zc 975.307203 WARNING: cell 2932552 of thread 2 has NULL face pointer 3.Error: Build_Grid: grid error. Clearing partially read grid" and "Null Domain Pointer" i was wondering if anyone can shed a light on what this means. Thanks |
Re: Fluent, Grid Builing Issue
I have had an error similar to this before where Gambit did not export the entire mesh because the hard disc was full.

Hmm. I don't think thats my problem. :(

Re: Fluent, Grid Builing Issue
Did you check the quality of grid? Just check if it has some negative elements because NULL DOMAIN POINTER comes usually in that case.

Re: Fluent, Grid Builing Issue
you should check to make sure no duplicate edges on the geom.
