[ICEM] 2D ICEM Mesh Problem

adamz1 · February 11, 2013, 09:04

I am a beginner in CFD and trying to mesh a 2D pipe y-junction. When I generate the mesh and then try to read it in Fluent, the following error pops up:

Reading: fluent12.msh"...

Clearing partially read grid.
2351 nodes.
2200 quadrilateral cells, zone 21.
4250 2D interior faces, zone 22.
280 2D wall faces, zone 23.

WARNING: Cell 1980 of thread 21 is missing face 3.
Cell Centroid is (0.031976, 0.003457).
Clearing partially read grid.

Error: Build Grid: Aborted due to critical error.
Error Object: #f
Done.

Error: access: unbound variable
Error Object: set-vars!

Error: access: unbound variable
Error Object: get-var

Could someone please have a look at it and tell me where I go wrong. I will attach the mesh files: https://docs.google.com/file/d/0B_dB...it?usp=sharing

topology is not good at intersection

you made a triangle at intersection. Is it playing any important role?

Thanks for you reply. I did it because I thought it would work. Could you suggest how I should change it to make it work?
