navier stokes no-slip element normals

[mark smith]

Hi Elmer team & users,
In a coupled heat and fluid flow problem does the direction of the surface mesh normals matter? in particular and inlet surface, outlet surface and heat flux load surface?
For no-slip surfaces Peter has already told me that the normal direction is unimportant, but what about other BC's?
Thanks in advance,
Regards
Mark

Hi Mark,

I don't know the answer. But I dare to ask if you have looked for it in the Models Manual...?
