Hi all,
Could any body help me in large mesh generation problem. I need a dense mesh in a annulus region of a cylinder. When I mesh it the size of the exported mesh reaches more then 2GB which crashes gambit. So I decomposed the geometry into four quarter cylinders. After that meshed each one individually, having size about 700 MB which is easilly exported by gambit. Merging those parts using tmerge utility I get a final_mesh. Now fluent does not load that big 2GB final_mesh, whereas penFOAM reads it. But any solvers of openFOAM does not run.Running the solver shows that there are some unwanted interfaces/walls have come. I meshed the geometry in gambit once using BCs and once without BCs, I found in both cases the tmerged mesh have too many walls/interfaces which are not required to me neither I had set them during mesh development. So my question is that how to remove those interfaces/walls. Since I can not load final_mesh into gambit/fluent to remove the interfaces/walls because it has size of 2GB which causes crashing problem in gambit/fluent. Further, could any body tell how to set boundary condition in a such cases where I need to export meshes in parts.
For some information I am working in dual core processors having RAM 4GB and 32 bit precision. Please let me know if any information is needed to resolve the problem.

thank you
