Meshing in parallel
Can I launch Ansys Meshing in the parallel mode? :confused:

Thanks. I already have read this thread. But I don't understand how to launch Ansys Meshing in parallel.
I know that in Fluent or in ICEM I can specify the number of the processors. Can I do this launching Workbench and working in Ansys Meshing?

I guess this might be the solution to your problem

workbench : Tools >>> options >>> Mechanical APDL . Here you can specify the No of processor and / or GPU support.

Far May 11, 2012 09:42

This is the solution
In ansys meshing go to tools >>> options >>>common settings >>> Parallel processing. :)

Thank you very much!!! I have found it!!!

I already set follow your comment but Ansys meshing still use only 1 cpu. Please advise me more

It should work. some snapshots will definitely help to identify problem.

ch_ohm June 13, 2012 00:38

I mean I set in >>tools >>> options >>>common settings >>> Parallel processing. I set 11 core but in the " Task manager" still show cpu usage is 1 :( So please let me know how to make it happen. thank

Parallell meshing will come with v15 and a beta release in v14.5 :p

ch_ohm June 15, 2012 09:03

Really ? I think the current version is 14. So, could you please let's me know about how long about that version will release ? thank you

RoJ June 15, 2012 15:59

This is just what I have heard. My guess is that v 14.5 comes in August or in September. I am looking forward to the parallell functionality !

Thank you very much

Hi I am using Ansys 14.5.7 and i have the same problem like ch_ohm. Set up to parallel but still meshing in sigle mode... What's the use for the parallel settings? Is there no chance to mesh parallel now with 14.5.7?

Parallel Meshing
Hello all,

Parallel meshing has been a new feature in Ansys 15. It was not available before. Now one can assign particular no. of cores in meshing a model. the requirement is minimum 2 Gigs of RAM per core. so if you have a 4 core processor, you would need minimum 8 Gigs of RAM.

It has been reported that already Ansys 15.0 meshing is around 3-4 times faster (of course depends on model and method). but it is definetly faster than the previous versions.


P.S: You dont need HPC license to access this feature :)

Parallel meshing in v15 is on by default and has been said is unconnected with HPC packs. It takes the form of assigning different parts to different processors, so may not show any extra improvement if you only have one part!.

It is definitely worth while making sure that the number of processors active is less than the number you have on your machine, if you want to use it for anything else at the same time as you mesh.

The new changes in the mesher are really very impressive though

Ansys 15 Parallel Meshing??
Has anyone got this to work? I have specified the number of processors in ICEM 15 and from the workbench in mechanical APDL and from within the meshing modeler. But it still only uses about 14% of my CPU........

gpu acceleration
I can get gpu acceleration working though i think :)

Parallel meshing in v15.0 works for more parts. If your model is only one part, it won't run. At least it did not work for me (it used only one core). You can split the model in different parts and it will work :)

Hope this helps a bit :)

Hello Folks,

I am trying to use Ansys meshing 15.07 for the physical preference of CFD. I set number of CPUs for parallel meshing to 11. My machine has 30 cores but it does not seems Ansys uses more than 1.(task manager)
Any idea would be appreciated!
