SU2 freezes when using large number of probes

[BerkeCan97]

Hi,

I had case where I had to extract data from large number of points, so I wrote script to add probes to the given locations. When I used only a few data points, the code seemed to work fine and SU2 was able to find the nearest nodes to the given coordinates. However, when I used around 13 000 nodes, SU2 seemed to stuck. I have waited very long time, so I do not think that's the issue.

I have now switched using paraview to interpolate data but It would be convenient not to store the flow field for each solution.

• [x] Looking for similar problems on GitHub or CFD-Online (https://www.cfd-online.com/Forums/su2/).
• [x] Updating to the newest version of SU2 (either develop, master, or the pre-built executables https://su2code.github.io/download.html).

Can you share an example? Does it work ok with 100 or 1000? It was never designed for handling that many probes, so it may just be very inefficient (slow) but not frozen

I had managed to get 40~ points to work but that was with a smaller mesh. As you said, it is probably very inefficient. I had left it to run overnight with 640 cpu cores but the preprocessing wasn't finished when I came back tomorrow.
