Particle-wall force using DEM

Dear forum,

Is there a simple way to extract the particle-wall forces in a DEM (or CGP-DEM) simulation? I was thinking about monitoring reaction forces on particles situated on specific locations, but I was wondering if there is a more straightforward way of doing it. The same question applies in the case an STL internal wall is used.

Thank you for your help!

SInce version 22.3 MFiX can save force chain data as VTK files, does this help?
