Hi Guys,
I used snappyhexmesh first normally and then with parallel Servers using decomposePar and reconstructParMesh... Although it was quick using parallel Servers but the mesh Quality and consequentally surface Quality was compromised. Has anyone also seen similar phenomenon before? If yes, is there a way to control this? I was using on test geometries but when I will the bigger and more complex geometries, parallel meshing would be unavoidable.
Thanks
Vineet

The only difference betweeen two approaches is how I use snappyhexmesh in my .sh script.
