Reply To: Sedimentation of one particle
I referenced the article in order to point out that the respective scenario can in general be investigated with OpenLB. A different output is to be expected for your 2D version (compared to the referenced 3D version) as the surface force to volume force ratio is significantly different for the same parameter setup. You need to be aware that transferring a real-world physical problem, which is inherently three-dimensional, into a 2D version is not straight forward (as it can be reasonable to have a 2D circle both represent a Cylinder or a Sphere in 3D depending on the assumptions). If you want to use the exact parameters used in the publication, you need to switch to 3D instead. If you want to stick to 2D you may want to look for a published 2D version for respective reference parameters.
