Reply To: Cumulant collision operator
Dear eulerboiler,
that is correct, we have a cumulant dynamics in OpenLB 1.8.
It is however limited to a specific lattice in three dimensions.
You could try yourself and implement a 2D version (if you have a reference with the specific equations to be coded).
If you need support for these kind of things, please consider visiting our yearly spring school (https://www.openlb.net/spring-school/).
Otherwise, you are welcome to share your progress in this forum.
