Calculation of boundary normals
 

Hi,

Can anyone please point me to the part of the code which calculates the boundary normals?

I believe the normal components can be output in the variable Normal using:

for the iVertex on the boundary iMarker.

However, I am not sure how (and where in the code) the value of these normal vectors are calculated based on the input mesh file.

Thanks,
Mandar

Hi Mandar,
Take a look at

void CPhysicalGeometry::SetBoundControlVolume(CConfig *config, unsigned short action) {

in geometry_structure.cpp

and CVertex::SetNodes_Coord

in dual_grid_structure.cpp

Best,
Francisco

Hi Francisco,

That helps!

Thanks a lot,
