low Re=0.1 laminar flow over a sphere
 
I've tried laminar model,3 k-e models,SST k-w model and some of low Re k-e models,which gave me the results of maximum total pressure coefficient 60+,while that's supposed to be 1.When using the same mesh and raising Re to 150,everything return to normal.I also checked the total pressure coefficient distrbution along the flow direction,which remained a constant 1 until the sphere made it a rapid increase.Obviously it was the near wall region that caused the magnification of this total pressure. So,is there any specific low-Re laminar model i can refer to or is this a bug of fluent?
