Thank you Adrian for the prompt responsse. I really appreciate it. At line 97 if I change N to 64 and Re 800 it gives me resoulation N=20 when I check it in data.dat file after the execution, which does not make any sense to me. Yeah I did read the User Guide also the article ” OpenLB—OpensourcelatticeBoltzmanncode” but cant get any clue.
In // Choose turbulence model or collision scheme section I uncommented #define WALE but cant find any info during compilation or after execution that Smagorinsky is activated and I am using that specific collision operator.
Any guidence would be a great help.
best
