Pointwise V18 is now available for download and production use. This is a major new release that greatly expands the software’s core meshing functionality as described below.

Quad-dominant surface meshes can now be generated. This new technique is a highly automated method for generating unstructured meshes consisting primarily of quadrilaterals with relatively few triangles.
T-Rex (anisotropic tetrahedral extrusion) has been extended to allow quad-dominant surface meshes to be used as the initial extrusion front for the generation of unstructured hexahedral layers.
Surface meshes (domains) and volume meshes (blocks) can now be retained, created, modified and examined in “mixed cell” format – a mixture of quadrilaterals and triangles for domains, a mix of hexahedra, tetrahedra, prisms, and pyramids for blocks.
Tetrahedral mesh cell sizes can now be controlled with geometry-based clustering sources.
