Sorry, I can't find that one myself... (If anyone out there still has a copy, I would appreciate it).
It is pretty easy though. What are you looking for? Hexa or Tetra Prism? Simon |

Hexa produces a better mesh, with better quality and requires less elements to fill the volume. It is also much better at capturing the near wall viscous effects...
However, for complex examples, Hexa may be relatively difficult to implement. It can also have an issue with propagating mesh counts thru unimportant areas. If your real model was complex, tetra/prism might be better because it effortlessly fills any shape without needing you to figure out the topology. If you really just want to do a simple blade in a passage, the hexa topology is pretty simple and I would recommend Hexa. Do you have access to ICEM CFD Hexa? Do a couple tutorials. You would need them to understand my instructions anyway. If you still need help, ask again then. Simon |

Thank you so much simon for very clear and brief reply. Thanks alot.
I will start doing hexa nesh tutorial in ICEM. I dont know that much about ICEM CFD Hexa. Is this different from ICEM CFD? I need a mesh for whioch i can write script easily, that means if my points will be chnage it produce new mesh easily. o which one is the good option by taking this consideration into account? Quote:

ICEM CFD Hexa is a subset of ICEM CFD... ICEM CFD is a collection of tools of which Hexa is one... Full ICEM CFD includes Hexa, but some users may have ICEM CFD Tetra (a subset of capability) which does not.
All of ICEM CFD is scriptable. Companies like GE script hexa for all their turbine blade analysis. Do you have a parametric geometry or are you wanting to build the geometry from a script in ICEM CFD? Perhaps the hexa demo's on our youtube site will help... www.youtube.com/ansysinc Best regards, Simon |
