Intersection
is a powerful mesh manipulator which facilitates modelling of
complex surface geometry. The intersection curves are defined
along the points spatially shared by two or more independently
created surface meshes. They split each of the surface meshes
into parts. All the mesh parts edged with a common intersection
curve are inter-connected at the nodes on the curve.
The mesh elements crossing over the intersection curves are removed.
And then, the gaps are filled by elements newly generated in align
with the intersection curves.

|
Conversion of quadratic
elements into linear
|
|||
|
Meshes can
be refined by subdivision or by convertion of linear elements
into quadratic order. Reversely, quadratic elements may also be
split into linear elements. These operations of mesh refinement
are applied to the whole model at once, and cannot be undone.
