[Nek5000-users] How to assembly different geometry

Hi Alessandro,

I believe the problem with the box file that you pasted is that the boundary conditions are not of required length. Each boundary condition must be exactly 3 characters long, and the first boundary conditions that you specified for Box 4,5,6 and 7 is 4 characters long.

Deleting one character from those empty boundary conditions makes them of the right length, and genbox runs fine after that.
