Thanks for such a nice video. My question is how I can probe over a surface not over a line or on a point? I want to know what is the airflow velocity inside a cylinder on a surface with a dimension of 50 mm x 50mm? I want to define the mean airflow velocity at the point with coordination of (195, 0, 50) on a surface with dimension of 50 mm x 50 mm around this point. The coordination of my surface around this point will be (145, 0, 0), (245, 0, 0), (145, 0, 100) and (245, 0, 100).
I have a lot of trouble to get probe data for chtMultiRegionFoam. problem 1: if I have a single probe in only one region, it works if I do a live run, but it does not work in post processing, with following error: "request for objectRegistry piece from objectRegistry waferTemperature failed available objects of type objectRegistry are 1(region0)" problem 2: if I have probes in different regions, only one of the probes appear in post processing folder. Do you know how to make it working properly? Below is an example of my probe file: type probes; libs ("libsampling.so"); name pieceProbe; writeControl writeTime; writeInterval 1; region piece; fields ( T ); probeLocations // piece ( (0 0 0.000881) );
Yes you can do that as a function object in controlDicl , and you can also do it in paraview by automating the post-processing (like in this video ua-cam.com/video/5pNJMiq7X58/v-deo.html )
Thanks asma your videos are amazing it helps a lot.
thank you for this wonderful tutorial!

Another great video. Thank you!
Girl, you are amazing!
I like to leave another tip. Please note that user needs to specify the region name (e.g., " region solid") if your model includes the multi-regions.
Thanks for your contribution 👍🏻

Hi Asma
If want to sample data from multiple lines do I have to create multile singleGraph scripts?
Yes you can do that as a function object in controlDicl , and you can also do it in paraview by automating the post-processing (like in this video ua-cam.com/video/5pNJMiq7X58/v-deo.html )
Thank you !!!
hi, what is the unit of the pressure from probe location? is it pascal?
Hi, OpenFOAM always uses International System units.
Well done!
Is the process same if I run in parallel?
As far as I tested, the parallel processing does not impact the probes results.
@@CFDAsmaaHadane my probes give zero values if I run solution in parallel. Any solution?
hello Asma i have an issue in openFoam can you help me
