Lattice creation failure

Coreform Cubit 2023.1 RC 33658 - Fedora 37

I’m having a play with the lattice capabilities following the instructions here 14 Cubit Workflows, but when in run the following I get slicing errors - could anyone elucidate?

cubit.cmd('reset')
cubit.cmd('create Cylinder height 1 radius 0.2 ')
cubit.cmd('surface 3 interval 20 ')
cubit.cmd('surface 3 scheme pave')
cubit.cmd('mesh surface 3')
cubit.cmd('volume 1  redistribute nodes off ')
cubit.cmd('volume 1  scheme Sweep  source surface 3    target surface 2   
sweep transform least squares ')
cubit.cmd('volume 1  autosmooth target on  fixed imprints off  smart smoot
h off ')
cubit.cmd('volume 1  redistribute nodes off ')
cubit.cmd('volume 1  scheme Sweep  source surface 3    target surface 2   
sweep transform least squares ')
cubit.cmd('volume 1  autosmooth target on  fixed imprints off  smart smoot
h off ')
cubit.cmd('volume 1  redistribute nodes off ')
cubit.cmd('volume 1  scheme Sweep  source surface 3    target surface 2   
sweep transform least squares ')
cubit.cmd('volume 1  autosmooth target on  fixed imprints off  smart smoot
h off ')
cubit.cmd('mesh volume 1 ')
cubit.cmd('build uspline volume 1 as 1')
cubit.cmd('fit uspline 1')
cubit.cmd('build uspline lattice uc "octettruss" base spline id 1 filename
 for vtk vis "cylinder.vtk"')

The error is

ERROR: Slicing error on thread 0.  Unspecified slicing error
ERROR: Command Failed.

Hi Andy,
Ah. That is because the lattice functionality requires a license to Coreform Lattice GC. 13 Coreform Lattice GC

I apologize that this is not well labeled in the documentation - will get that cleaned up. I’d be happy to get you a trial license if you’d like to try it out?
