Generate a 2d model of a semicircle

[bright-men]

We can generate two-dimensional circles using Neper, and there are many applications in three-dimensional cutting. But I do not know what command should be used to cut a circle to generate a semi-circle.

See split in -domain. Here is an example:

neper -T -domain "circle(1):split(x)"  -n 100 -dim 2
neper -V n100-id1.tess -print img
