Dear Foamers,
In OpenFOAM we are able to define probes that are moving with a moving mesh which is very useful for example in pressure probing of moving objects. this capability unfortunately I think is not available in Foam-Extend versions, which is a very big flaw especially for FSI applications. the following lines which are in probes.H files of OpenFOAM are missing in Foam Extend versions: Code:
//- Fixed locations, default = yes // Note: set to false for moving mesh calculations where locations // should move with the mesh //- Interpolation scheme name // Note: only possible when fixedLocations_ is true word interpolationScheme_; bool fixedLocations_; Thank you Ali |

I did solve this problem a while ago and I want to share it here.
it is quite simple to have probes moving with mesh. you just need to comment out the following lines from the probes.C file Code:
if (mesh.moving() || mesh.changing()) { cellList_.clear(); findCells(mesh); } |

Is there anything else I need to do? I commented out the part of the code but the probes are still not moving with the mesh although I added "fixedLocations false" in the controlDict.

Thanks for the fast reply. I will try it, but I am not too familiar with this. If possible, to make things a bit easier, can you share your code?

I also am having trouble with this exact issue, I tried your approach with commenting out the section and duplicating the probes folder to make myprobes, however it didn't compile correctly. I also tried just downloading your folder to my $WM_PROJECT_USER_DIR and typing wmake within it, without success. Do you have any suggestions as to what I might be doing wrong? I have fsi foam and waves2foam installed as well, do you think they have broken the functionality or your fix?
