How to calculate impingement angle with wall in MFiX-DEM?

Hi, I am planning to utilize MFiX for simulating erosion problems. The erosion model relies on the impingement angle between particles and the wall. Are there any variables embedded in MFiX-DEM for this purpose? If not, how can I obtain the normal vectors of contacting walls?

Hi @panm welcome to the MFiX forum

Please see the file des/calc_force_dem.f, in particular around line 275
