weird looking yPlus graph
1 Attachment(s)
Hi All,
I run a k-omega SST incompressible flow past a hemisphere (generated from setSet utility). I normally get the y+ values from the display screen, and a bit puzzled when see this graph. Could you suggest whether this make sense?
Here's my checkMesh results:
PHP Code:
