Hi

I have a machine with 32 cores and I want to be able to setup both classic Icepak and the AEDT Icepak so that it runs the "solutions" on multiple cores. I have already used the parallel CPUs setting and it works fine while the underlying Fluent backend is run, but while collating the data and finalizing the solution and loading it up, it does not end up using multiple cores. 

 

Thanks

Best

Hi Rishabh,

Thanks for using Forum to ask question. For the classic Icepak we just need to specify the number of processors in Solution settings–>parallel settings panel.  As you have observed, the parallel processors are used by fluent to solve using the multiple processors. For loading and post processing it uses one processor. 

In AEDT, however, different options and settings can be used to improve the efficiency of various Icepak processes

‐Pre/Post processing option

‐High Performance Computing (HPC) tasks

 

•Pre/Post Processing Option

‐Viewing the mesh with Mesh Viewer

‐Mesh quality calculations with Mesh Viewer

‐Plotting field overlay data

‐Field summary calculations

‐Fields calculator calculations

 

Please check the document or training material for details. If needed please create a support case in Ansys customer portal.

 

Thanks.

Hi Rabindra

I checked the pages but I still need some more help. I was able to setup all the options correct and since I am only running on the large local machine, I do not need to setup job scheduler or LSF. I see that my runs on the same model in AEDT Icepak take significantly longer than what they took in Classic Icepak. Can someone please help me with this?

Thanks

Hi Rishabh

Thanks for getting back to us. I guess you are importing the TZR in AEDT and using the same/similar mesh count and setup and using the same number of cores etc.

In any case, our support team can help with this.  It would be of help to create a support case and attach the files and provide related information.

Hello

Both classic Icepak and AEDT Icepak use multiple cores for post-processing and data collation, follow these steps:

1. Enable multi-core processing in the software settings.
2. Increase solution parallelism by adjusting the settings for how many cores or parallel tasks to use.
3. Check that the software is set to use multiple cores for post-processing and data collation.
4. Consider using a batch mode or scripting to automate tasks and take advantage of parallel processing.
5. Make sure your computer has enough memory (RAM) and fast storage to handle the workload.
6. If you need more help, consult the software documentation or contact the support team.

By following these steps, you can optimize the use of multiple cores and improve performance during post-processing and data collation in both classic Icepak and AEDT Icepak.

Thank you.
