Exporting ICEM Tetra Grid to Fluent with Hexa-Core

I've just recently started using ICEM Tetra/Prism and seem to be having problems getting my mesh files exported into Fluent. I import the geometry into ICEM in IGES format, tidy it up and name all the parts, mesh using the Octree method and then apply a hexa-core to the volume mesh using the Delaunay approach. Smooth the mesh, check it for all errors and possible problems and then export in Fluent_V6 format .msh file. The only possible problems that I'm not sure about are with Delaunay violations.
The problem is that then when I try to read the grid into Fluent I get a read error. I've tried ACSII and binary formats and neither work. I've also found that importing the grid with a pure Tetra mesh (i.e. no hex's) does work. So I'm thinking that the problem is how Fluent interprets the Hexa-Core mesh topology. The exact error messeage upon reading into Fluent is as follows: > Reading "C:\Documents and Settings\tim\Desktop\Sample-Assembly6.msh" 253326 nodes. 675151 mixed cells, zone 73. Error: read: face 1471627, zone 74. Reading Faces: failed while reading section 13. Clearing partially read grid. Error: Read aborted dut to critical error. Error Object: () Error: Error reading "C:\Documents and Settings\tim\Desktop\Sample-Assembly6.msh". Error Object: #f If anyone has any ideas as to what I can do to correct this problem then any assitance would be very much appreciated. Thanks, Tim |
