Hi All,
I am having issues with importing my 2D mesh into Fluent. The geometry has a simple conical nozzle extending into a test section that has a truncated conical specimen placed inside. Its a PATRAN file created using ESI's CFD-GEOM. I did check my grid 100 times for flaws and found none. I tried different domain configurations to make this work but that was just a waste of time. When I break my grid into 2 different pieces i.e., nozzle and test section, I am able to import them successfully. But when it comes to the whole setup, the error message " Build grid: Aborted due to critical error" pops up and the the function window says " Cell centroid is xc: "(some value)" and yc : "(some value)"
WARNING: no face with given nodes. Thread 1, cell 22109
Clearing partially read grid.
Error: Build grid: Aborted due to critical error
Error object: #f "

Please suggest some good techniques to make this work.

it is 2d mesh?

A number of reasons can produce this error, don't know exactly which one?

1. may be negative volumes? or
2. a very very small volume? or
3. orientation of blocks/surfaces problem? or
4. Fastran didn't export file correctly or if you copy from another PC , incorrect copy.
5. may be more?

I have faced this a few times. I usually revisit my mesh and try to correct all the above I mention. You can do:

1. try to open in a serial Fluent, problem may be solved. or
2. export in any other format accepted for fluent like CGNS/NASTRAN from FASTRAN. If problem is still there you have to remake/correct you mesh.

@Far: It is a 2D mesh and I trying to import it into ANSYS 13,0.
@Ali: Thanks for the suggestions. I did try importing it in different formats but that did nit work either. May be I just need to fiddle around the mesh till it gets imported. Is there any other reason that you can think of ?

Your mesh must be on the x-y plane, a requirement of Fluent

try to load ur file in tgrid or icem!
