Dear Keino,
Thank you for getting in touch with us.
It seems that you are using the SetWeightingField function to import the weighting potential instead of the intended SetWeightingPotential function. To indicate to the AvalancheMicroscopic class that the weighting potential should be used for the signal calculations instead of of the weighting field, its UseWeightingPotential function can be used.
I hope this helps.
Kind regards,
Djunes
Thank you very much for your reply! I’ll try to give it a try.
Thank you very much for your reply! I tried, but the result is still the same no pulse signal output, my classmate had run with this code and got the signal successfully.
That is strange indeed. Could you provide me with the terminal output when running the script?
Hello,
Did you try to plot the weighting potential first, to see if it is correctly loaded?
I faced a similar issue recently because of the line 481 in ComponentComsol.cc. For some reason my weighting potential was set to invalid, so it was ignored by garfielpp afterward.

Thank you very much for your patience, this is the file output from my terminal.
1.txt (879.1 KB)
Is it possible that there is a problem with my software installation?
Thank you for your reply, my weight potential distribution is also no image！
Dear Keino,
I see nothing unusual in the terminal readout. The fact that the code can be run successfully on another device could indicate an installation issue. To make sure it is not the code, could you provide me with all the files by sending them to djunes.janssens@cern.ch? This way, I can try and run it myself and take a closer look. I will keep the discussion on this forum so it can be helpful for other users as well.
One small point, the code on lines 178-192 in your script are needed to make the header of COMSOL’s weighting potential map file compatible with the one expected by the import function?
Kind regards,
Dear FlorianBen,
Have you managed to find a solution for the ignoring of the weighting potential?
Kind regards,
I simply forced the value to be true in the source file.
It’s not a nice workaround but otherwise I had the same issue: the weighting potential was correctly loaded by garfield but not used for plotting and signal calculation.
Thank you again for your reply！
The explanation of the code in lines 178-192 you understand is correct, because the file exported from COMSOL using parametric scanning will have information about each parameter.
In addition, when I was looking for installation problems, I found that I have an example (Geant4GarfieldInterface) that runs with an error message like the one below, and I don’t know if this has anything to do with the problem I’m facing.
This looks like a different problem to me. Is your ROOT installation compatible with the compiler you are using?
Kind regards,
GCC 7.5 (on Ubuntu 18.04) does not really support c++17. You need to choose c++14 or c++11 (the same for all involved packages).
Thank you for your reply！ I don’t quite understand what you mean, are you trying to say that I need to update the compiler version? Or do I need to reinstall Ubuntu or ROOT? (I’m new to VMs and don’t know much about them, so sorry)
I would be grateful if your answer！
Kind regards,
I have sent the file to your email address, did you receive it?
Dear Keino,
Did it work in the end? If not, I have pushed a possible solution to the repository. Let me know if it helped.
Kind regards,
Djunes
I’m sorry for not replying in time！
The solution provided did not solve my problem, and also found another problem, that is, it is likely that the weight potential reading problem, because when I open the .txt file when the phenomenon of a black screen, I do not know if there is an error when reading (or open the text of the software problem)
