Fluent repairs left-handed faces

nch · January 21, 2019, 07:18

Hi everyone,

After a mesh checking I got a warning message about the presence of left-handed faces in my mesh.

I tried to fix this issue by using the Fluent tool "repair" and it's been able to sort out the problem.

My question now is: does anybody have an idea about what Fluent actually does on the mesh faces in order to fix wrong handedness?

Thank you,
Niccolò

It just tries to flip the handedness to see if it can make a cell that makes sense (positive cell volumes).

Thank you! So, nothing complex!
