Hi Dear all,

I am using hypermesh 10 for creating a CFD mesh for a flow analysis, was attempting various options given in the package,

the model is basically a simple geometry Fig1 , a 1m x1mx1m with a hole of Fig2 25cmx25cmx50cm , due to this drastic changes there were issues in maintaining the aspect ratio .

as a result the number of elements were huge ...approx 28 lakhs . due to this the file swells to around 120mb , and the app is not able to retrieve it back due to memory problem.

trials:
1> regular hex mesh using drag and solidmap options: good results but elements are large in no.
2>volume mesh : elements fail near the hole

i would badly need help form this forum regarding:

1> CFD meshing in hypermesh
2>using the Wind tunnel meshing module in hypermesh



I am open for help in the fields of structural analysis using hypermesh and optistruct ond nastran also optimization

Not sure what you are doing to get this? You should be able to do this in the CFD subpanel panel under the tetramesh panel. Is that what you are doing? Because the BL should be user-specified and growth rate of the tets also to your specification. Please confirm.
