Hi,

Is there a step-by-step tutorial for a simple CFD-DEM test case?

Best regards,

Hi Jan,
the files you get when dowloading from the git also comprise a number of testcases for the different solvers.
Cheers,
Alice

Thank you for your answer.
I successful ran the "settlingTestMPI" test case. When I ran the "HopperEmptying" test case and get the following error message:

#insert the first particles so that dump is not empty
dump myDump all stl 1 post/dump.stl
ERROR: Illegal dump stl command, you have to write one file per time-step by using the '*' in the file-name

Do you know where the problem could be?
It works if I only use LIGGGHTS without fluid coupling.

Cheers,
Jan

Hi!

This is due to changes in the LIGGGHTS version, please use the line:
dump myDump all stl 1 post/dump_*.stl

in the in.liggghts* file.

Cheers,
Chris
