Pointwise V17.2 R2 Is Now Available
Pointwise Version 17.2 R2 is now available for download and production
use. The main new feature in this latest release of Pointwise is an
improved hexahedral-layer capability in the T-Rex (anisotropic
tetrahedral extrusion) hybrid meshing technique.
Hexahedral Layer Improvements in T-Rex
The manner in which T-Rex agglomerates anisotropic tetrahedra into
hexahedra was changed. This new algorithm has three main benefits:
- The extrusion is up to 33 percent faster due to a reduction of the
number of cells on the extrusion front.
- The extrusion is more robust due to a simpler cell topology on the
extrusion front and advances between 7 and 17 percent farther, so you
get more high-quality, hexahedral cells and overall lower cell count.
- Because of the simpler front topology, the number of cells in the
isotropic region decreased by up to 29 percent for further overall cell
Figure 1: Cuts through a hybrid mesh generated by the updated T-Rex for
this particular mesh, the time required to generate the anisotropic
cells was reduced by 46 percent, the number of agglomerated cells
increased 15 percent, and the total number of cells for the overall mesh
was reduced by 20 percent relative to the previous version of T-Rex.
Other Features in V17.2 R2
- Align View to Surface:
The orientation of view in the Display window
can be aligned with the normal vector of any selected surface. Also,
view transitions to saved orientations can now be animated.
- Updated CAD File Readers:
In addition to implementing the latest
libraries from our CAD reader provider, the reader has been implemented
as a separate process for improved robustness.
- Drawing Guide:
A drawing guide consisting of an array of vertical
and horizontal lines can be overlaid on the Display window as a visual
aid for aligning points on the screen for various operations. Also, the
option to disable snapping to a selected point (previously available
only in the Tweak command) has been added to all other commands using
the 3D point placement tools.
- New CAE Solver Support:
Native support is now available for the Edge
and LAURA flow solvers.
- Project Distribution:
A connector's shape can be projected while
retaining its distribution attributes (whereas the distribution function
had always been changed to the general type).
- Save Selection:
Using the Save Selection As command, selected
entities (and all other entities on which they depend) can be written to
a new PW project file. With the Save Environment As command, all
settings – defaults, layers, properties, views, saved examine cuts,
rules, etc. but no entities – can be written to a
PW file for loading
at the beginning of a new project.
- Scripted Entity Selection:
Two new Glyph commands provide more
control over entity selection. One command returns a list of the
currently selected entities. The other allows specification of the
entities to remain selected upon script termination.
