Hi all,

I am tryng to simulate the flow around a sphere... I think it is one of the simplest geometry in the world...

But I get an error when I try to mesh it with the snappyHexMesh command.

The error is reported below. Also, I attach both my geometry and the files I edited.

Could you help?

Thanks a lot,

Samuele

Code:
samiam@einstein:~/Desktop/sfera$ snappyHexMesh
