Hi all researchers! I am working on simulation of flow past a square cylinder using IB-LBM MRT method at Re=2100. I am having 4096 by 2048 mesh cells in a 50D by 25D domain where D=0.1 and I am looking at the results that on the same number of simulations the flow seems to be attached at Tau=0.505 while it seems to be OK as at Tau=0.5025 while all the parameters are kept same. Could anybody please let me know that how far this thing depends on relaxation parameter as the results are quite different and strange. The Z vorticity contour images are attached for reference Anxiously waiting for expert opinions and guidance.
Best Regards
Hi, im working on simulation of flow past a square cylinder with MRT method. I have the same problem with yours. I wonder that could you solve the mistake related set of relaxation parameter.
