Pointwise Version 17.2 is now available for download and production use.
The main new feature in this latest release of the software is an
extension of the T-Rex hybrid meshing technique to create layers of
Unstructured Hexahedral Layers
Through an extension of the algorithm that post-processes the tetrahedra
generated by the T-Rex advancing layer technique (anisotropic
tetrahedral extrusion), the high aspect ratio tetrahedra created by
extrusion from a quad surface grid can now be agglomerated into
At its core, T-Rex is an advancing layer technique that starts from a
triangle surface mesh and extrudes layers of high aspect ratio, right
angle included tetrahedra near walls, wakes, and other features. Those
tetrahedra are post-processed (optionally) by combining three successive
tetrahedra into a prism.
The ability to post-process the stacks of extruded tetrahedra into
hexrahedra begins with a quadrilateral surface mesh off of which the
first extruded cell is a pyramid. The regular T-Rex extrusion takes over
from there. The cells are then post-processed into stacks of hexahedra.
See Figure 1 for an example.
This extension also adds to T-Rex the ability to have an existing
quadrilateral mesh serve as a boundary condition for a T-Rex prism

The Draw Curves button on the toolbar has been modified to be a
dropdown menu allowing you to either select the default curve type and
begin drawing or choose another curve type which then becomes the
A half-symmetry grid can now automatically be mirrored on export to
create a full grid.
Blocks with internal faces, both closed and open, can now be
The quality of shaded surface display has been improved through the
use of OpenGL shaders (on supported hardware). Also, a user-positionable
light source has been added as shown in Figure 2.
Entities selected in the Examine, Rules command remain selected when
the command is closed. This way you can use the Rules to identify bad
grids, select them, and have them remain selected for the Solver or
Figure 2: The new user-positionable light source can be fixed in space rather than always at the viewer's location.
Expanded Linux Support
In addition to Red Hat Linux, Pointwise is now supported on SUSE Linux,
CentOS, and Ubuntu.
Upgraded Solver Compatibility
Pointwise now exports pyramids to Nastran files as true pyramids
and not degenerate prisms.
Pointwise now supports the latest version of the CFD file standard,
CGNS v3.2. With this upgrade Pointwise is now able to export both
unstructured and structured zones to the same CGNS file.
Pointwise is now compatible with NASA's FUN3D flow solver.
Pointwise can now export to the GAMBIT neutral file format. GAMBIT
neutral files are ASCII based and store mesh and boundary condition
The Pointwise STAR-CD v4 CAE exporter plugin now uses the SDK face
Pointwise is now compatible with Cradle's SC/Tetra v9+ flow
