Reply To: Simulation of Single sphere settling in water
we have several models implemented in OpenLB. The one your have chosen is a sub-grid model with no-back coppling. So what you observe is corect.
An overview about particle-fluid models you will find in https://publikationen.bibliothek.kit.edu/1000061601 .
Further, I recomment our next spring school. There, we offer a talk and hands on on at least two different model implentations in OpenLB.
