How to more easily export AcuProbe results from multiple simulations of SimLab? Also, what kind of r

Hello experts,

I've been running a large number of simulations in SimLab and need to export the AcuProbe results for each one. Currently, I have to open the log of each simulation and manually export the results, which takes me around 2 hours or more just for this task.

Here you can see a folder showing a quarter of the simulations I'm working on:

Also, when I use AcuProbe to export a variable, I do it manually for each simulation:

My question is: Is there a way to more easily export the AcuProbe results from multiple simulations?

The results I get directly from SimLab responses aren't helpful because I can only obtain the maximum or minimum value of the variable I need.

Additionally, I'd like to know what kind of results AcuProbe provides. Are they averages over all the elements of the surface or another type of result?

I believe that the results provided by AcuProbe are averages, because when I compare the results in SimLab with Query Results, and export the data and find the average of that variable in Excel, the results are very similar although not equal. I just want to be sure about what type of results they are.

I would greatly appreciate any help or suggestions!

    You would want to use the command-line utility acuTrans to generate files with the integrated surface output variables - that you see under the Surface Output tree of AcuProbe. This is the Help page for acuTrans:

    https://help.altair.com/hwcfdsolvers/acusolve/topics/acusolve/post_processing_programs_acutrans.htm

    Table 7 on that page has the list of available integrated surface output quantities. Table 25 has the definitions for those integrated variables. Just above that table is description and an example of the acuTrans command to use with -osi to get integrated surface quantities. acuTrans -h gives the full list of options.

    If you have the HyperWorks CFD Solvers package installed, you can run acuTrans from the AcuSolve Command Prompt. ( Windows Start > Altair <version> > AcuSolve Cmd Prompt <version>

    If you only have SimLab installed, go to this location (default, so you may need to adjust if SimLab is installed in a different area):

    C:\Program Files\Altair\2024.1\SimLab\bin\win64\solvers\Acusolve\acusolve\win64\bin

    and double-click acusim.bat to open the AcuSolve Command Prompt.
