Hypermesh-fluent reading

sudha · July 18, 2011, 03:14

hello dignitaries!

i am a student working on heat ex-changer design for my thesis, to model the 90.deg symmetry, i have used the HYPERMESH and wrote a case file for FLUENT.

while i was reading the case in fluent in parallel processing mode, it is staying at

Parallel variables...
Building...
grid,

auto partitioning mesh by Principal Axes,
distributing mesh
parts....,
face....,
nodes...,

i have waited for it to proceed further for two days.

i am working on 8 core 16GB machine.
my mesh size is 5.4million

someone who can advice pl. help me.

Has this problem been resolved?
Try exporting the mesh from HM as a Nastran file (.nas or .bdf) and then import into Fluent.
5 mill is not too big for a 16GB machine.

thank you for your concern!

the problem is resolved. there were some files missing while i was writing a fluent case from hypermesh. so i tried to write in small parts and then read it in fluent.

may be this is not the way to do it, but still it worked.
