I’m PhD student at University of British Columbia. My current research is using LB for mixing tanks. I don’t want to use commercial software for this because I want to develop something and contribute to the opensource community. I have been over the documentation on OpenLB and have only been able to find a very interesting journal article, “An extension of the Lattice-Boltzmann Method for simulating turbulent flows around rotating geometries of arbitrary shape”. Is there a tutorial on rotating geometries or even an example code?
there a several approaches to realize a rotating geometries. In the paper it was realized by boundary conditions only. Here, https://www.youtube.com/watch?v=Msh2iyG6-ho we used a moving frame (basically you get a force term (there are funcztors in OpenLB to do that easily)). We have no example ready to give you. Maybe, it is a good idea to come to our next spring school which is soon to get started and in the last part we help you with your problem.
