Good morning!

I wanted to test the new beta options in CFX 17.1: "Monitor Run with CFD-POST (beta)" while the calculation is still ongoing.
So far, I found out that this is only possible on user surfaces. (Is that correct?) Those are the steps I took:
- I created 3 user surfaces in Post (such as a YX-plane),
- exported them to a *.csv file,
- imported them in PRE as user surfaces
- created 'Monitor Surfaces'
- added the 3 user surfaces (output frequency: every timestep, variable: velocity in stn frame)
- wrote solver input file
- started solver

After one outer loop, the calculation stops with the following message (complete, censored out-file attached)

Parallel run: Received message from slave

I can't attach screenshots since I would need you all to sign NDAs first

Any ideas how I could solve this problem?

Thanks in advance.

Best,
Maxim

If you are testing a new beta option it is unlikely the forum can help you. You will need to contact ANSYS support. And this is especially the case if you have found a bug, as the purpose of testing beta features is to find bugs and you should report it to get it fixed.

thank you Glenn for your answer. That's what I almost expected. I plan to contact support at some point

I have just experienced the same issue, however I got the error message after ~430 time steps. I had heard from colleagues prior to attempting to use this feature that it's less robust when trying to monitor more than one surface.

Did you find a definitive answer as to what causes this?

[-Maxim-]

No, I gave up after a few tries. I haven't used that feature any more since then.
When it comes to monitoring, CFX is really lacking behind StarCCM+ and OpenFOAM.

[tias]

Shame. Thanks for letting me know. Due to other constraints, I'm tied to CFX for now. Hopefully I can find a way such that I don't upset it. Cheers

Good luck! If you find a way, please report back
