Build grid: Aborted due to critical error
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?
Regards Hybrid |
@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!

I have same problem you can see problem curve when uncheck shells under mesh and associate that curve , on the other hand if you working sharp tail edge and you should create a curve this is important which is associated curve of airfoil |
negative volume cells
In my case (ICEM CFD block mesh), I had plenty of negative volume cells because of inverted blocks.
Then I fixed inverted blocks by >> Blocking/BlockChecks/method/Fix Inverted Blocks, and it solved the problem. |
thank you, your solution worked very well

hi, i fixed those inverted blocks too. even then it shows the same error. so,what else would be the problem?
