Hello,nIn my case I am using SST model. My first cell height is an extremely small value (around 5*10-7 m) When I use this I get the floating point error. When I use a coarse mesh and proceed my simulation proceeds without any issue.nSo the problem is with my mesh. But I am not sure how to fix it. I use inflation and make my first cell height the above value.nPlease any help would be highly appreciated. Been stuck for days in this now.nThank you.nRegardsnDilinin
