Meshing of tessellations cut by ecylinder

[Sofia-Y]

This example works just fine in 2D for both "quad" and "tri" elements. Also, worked for 3D "hex" elements but not for the "tet" elements.

Any help, please?

$ neper -T -n 1111 -id 1 -oricrysym cubic -ori uniform -format tess -transform "cut(ecylinder(0,0.5,0,0,0,1,1,0,0,0,1,0,0.5,0.05))" 
$ neper -M n1111-id1.tess -elt tet -format 'inp'

It is a bit disappointing, but as it turns out, -transform cut(ecylinder(...)) will generate the tessellation just fine, but meshing is not supported yet...

Fixed in 4.4.1.
