[The following is an email that Manoj sent the tech support staff at PADT. I thought is was perfect for a The Focus posting, so here it is – Eric]
First of all I found out a way to get Mesh Generation time (if no one knew about this). In ANSYS Mechanical go to Tools->Options->Miscellaneous and turn “Report Performance Diagnostics in Messages” to Yes. It will give you “Elapsed Time for Last Mesh Generation” in the Messages window.
Next I did a benchmark on the Parallel Part by Part meshing of a Helicopter Rotor Hub with 502 bodies. The mesh settings were getting a mesh of about 560,026 elements and 1.23 million nodes.
I did Parallel Part by Part Meshing on this model with 1,2,4,6 and 8 cores and here are the results.
Can I say “I LIKE IT!”
1 core: 172 seconds (1.0)
2 core: 89 seconds (1.9)
4 core: 52 seconds (3.3)
6 core: 38 seconds (4.5)
8 core: 33 seconds (5.2)
Of course this is a small mesh so as the number of cores goes up, the benefits go down. I will be doing some testing on some models that take a lot longer to mesh but wanted to start simple. I’ll make a video summarizing that study showing how to set up the whole process and the results.
