PISO's strange behavior at different meshes :(

Posted February 25, 2013 at 07:19 by skeptik

1. mesh quad+tri+3D extruded. at 17 grad most flow around airfoil is laminar

2. mesh only tri+3D extruded. at 15 grad flow behind foil is completely turbulent

so this pictures shows that we cannot get proper results for Cx, Cy due to bad prediction of the flow detachment.

try to find a solution, may be OF 2.1 will show better results
