Hi guys,

I got the folowing message when i was trying to generate hexagonal mesh on an impingement plate:
Running hexa-dominant mesher...
{expecting 2 shells on edge 152 769 found 3
error orienting normals, perhaps there is more than one region
error in output_boundaries
Hex Dominant meshing failed
Performing a mesh flood fill...
element containing material point FLUID_1/EXTENDED_FLUID_2_MATPOINT.1 was not found
done mesh flood fill
Can anyone tell me what is the reason for this?

Thanks in advance,
