Hi!
I have a little trouble with the command "bond_type harmonic"
if I use this command (bond_type harmonic) under LIGGGHTS works without any problem,
when cfdem coupling, I got this message:
"

I used before the command "bond_type gran"
I had the same message despite SEVERAL tests, so I decided to use the "type harmonic" to have an end of my problem simulation.
another point, when i using a pressure gradient , it will give me a message from the firsts iterations.
Thanks in advance
