I have a simulation that has a bit of set up in it.
Does all of the setup need to be done strictly in the liggghts enviroment and then in CFDEM simply read in the ligggghts' input file and run,
or can I do the setup in CFDEM? An example would be the following.
Compress Particles then uncompress particles and wait for the KE of system to drop below a specific value
Add CFDEM fixes
Then let CFDEM push the liggghts simulation forward with the runliggghts script.
I have been trying this and it leads to some weird results (particles explode). I know it is not because I am using too high of a time step for the ligghts simulation (runs fine when not running cfdem). Is it because I am using the wrong solver? I am currently using cfdemSolverIB. My particles have a diameter of 3mm and my domain is 100mm x 100mm x 100mm.
Any and all suggestions are welcome.
