[Nek5000-users] Problem converting 2d to 3d

[nek5000-users at lists.mcs.anl.gov]

Hi,

I created a 2d rectangular mesh using genbox,


then I tried to used n2to3 to convert this into a cylindrical pipe 
using  circular sweep but I get errors while loading the .rea file .

could some one help me fix this

Thank you
