Overview

Pointwise is our leading mesh generation software product for CFD, encompassing nearly three decades of technology development. The product features a modern software framework and workflow and provides tools like 64-bit support, multi-threading, and Windows/Linux/Mac portability.

These release notes are provided as a reference for the new features included in the latest version of Pointwise as well as any known issues that were resolved.

New Features

  • Pointwise now provides a new entity type for controlling local isotropic cell size for unstructured blocks. This new entity type, called a Source, provides a way to specify a target cell size in a geometric region that is independent of the grid entities and topology. For example, wake refinement can be achieved by creating a Source entity box located in the wake region with the appropriate target cell size, and any unstructured blocks that overlap this Source entity box will use the target cell size in that region when it is being initialized or refined.
  • The Draw Shapes command has been added to Pointwise to provide the ability to quickly create boxes, cylinders, spheres, and polyhedral for use as database entities or sources.
  • T-Rex can now directly create triangles and/or quads in 2D and mixed element blocks containing tetrahedra, pyramid, prism and hex cells in 3D. Controls for creating mixed cell domains and blocks can be found within the Grid, Solve command.
  • Pointwise can now generate quad-dominant isotropic domains consisting of triangles and/or quads using the Delaunay, Advancing Front, or Advancing Front Ortho algorithms.
  • Quad-dominant domains in Pointwise can be extruded into blocks via an updated normal extrusion algorithm.
  • Mixed cell blocks containing tetrahedra, pyramids, prisms, and hexes can now be imported and exported to CGNS.
  • Database shell entities (i.e. faceted surfaces) can be imported with any arbitrary polygonal shape. This includes triangles, quads, arbitrary polygons, and polygons with interior holes.
  • The T-Rex cell combination option available upon exporting a mesh has been relocated to a Combine T-Rex Cells command within the Edit menu. This allows users to combine T-Rex meshes from previous versions of Pointwise without having to re-initialize those meshes in Grid, Solve. The legacy Convert T-Rex to Prisms Edit menu command available in previous versions of Pointwise has been deprecated, but its functionality within Glyph is still available for those users who require it.
  • Pointwise now uses the Reprise License Manager (RLM) for license management.
  • Multiple blocks of varying types (i.e. structured, prism, unstructured) can now be joined into a single unstructured block in a manner similar to how unstructured domains are joined.
  • In Examine, the Cell Type (formerly the None option) function now allows volume grid cells to be colored by their type (hex, tet, prism, pyramid). This function also enables users to choose which volume cells are visible by type.
  • Information regarding number and source of the associated databases is now displayed in Examine for the Database Associativity function.
  • Quad cell warp is now a supported metric in Examine. Warp is the angle between the normal vectors of triangles that result from diagonalizing a quad. Since a quad can be diagonalized two different ways, the reported value is the maximum of the two diagonalizations.
  • Pointwise now supports high-resolution (e.g. QHD, UHD, 4K) monitors with graphics that scale up crisply with no loss in GUI or graphics interaction.
  • The Cell Count command has been updated to include itemization for an expanded set of entity types (connectors, domains, blocks) and cell types (quads and triangles). The command is now selection sensitive and provides both selection and project totals for each entity type. A new toolbar item has been added to print the table summary directly to the Messages window without having to open the command's panel.
  • The direction of rotational extrusion can now be specified implicitly by entering a negative angle of rotation.
  • The Set Boundary Conditions command now contains an option that allows previously assigned boundary conditions to be hidden from the Display window and from subsequent selection.
  • The right-click context menu now supports changing entity attributes.
  • Break points on database-constrained connectors can now be created at user-specified values of the U or V parametric coordinate.
  • Clickable links are now supported in the message window. Hovering and clicking on these links will perform various actions.

Resolved Issues

PW-20066 Two intersecting models could not be trimmed by each other with the Edit, Trim By Surface command.
PW-20062 Structured domains were copied, pasted, and mirrored. The interior of the resulting mirrored domains did not look like the original domains.
PW-20035 In Pointwise V18.0 Beta, T-Rex layers stopped prematurely off a convex 90 degree corner. The same mesh could be initialized with more layers off the corner in Pointwise V17.3 R5.
PW-20015 A domain was selected in the Display window while the CAE, Set Boundary Conditions command panel was open. The boundary condition to which the domain was assigned did not highlight when the domain was selected.
PW-19989 Negative volume cells were generated in a T-Rex block initialized in Pointwise.
PW-19946 A Pointwise project (.pw) file containing a single connector was opened in Pointwise V17.3 R5 and V18.0 Beta 1. The connector had the correct distribution and length in V17.3R5. In V18.0 Beta 1, the connector had a different dimension, length, and shape.
PW-19925 Pointwise was unable to export a grid to the CRUNCH CAE solver.
PW-19901 Pointwise exited prematurely when trying to initialize a mixed cell T-Rex block.
PW-19874 A source was copied, pasted, and mirrored. The mirrored copy appeared displayed in gray instead of orange.
PW-19863 For an isolated domain, the Examine diagnostic functions of Equiangle Skewness and Max. Included Angle provided different results dependent on whether the domain's associated database surface was present.
PW-19804 Pointwise was very slow exporting a large T-Rex grid to the Cobalt CAE solver.
PW-19802 Creating an unstructured domain on a portion of a cylinder failed.

PW-19676 A T-Rex domain was failing to grow layers at various locations along the connectors assigned to Wall boundary conditions.
PW-19675 A grid containing a large number of interior Fan boundary conditions took several hours to export to the CFD++ CAE Solver. The same mesh was exported to ANSYS Fluent in a few minutes.
PW-19651 Pointwise was unable to import some of the facets in an STL file.
PW-19647 Information about the growth of T-Rex layers was no longer appearing in the Pointwise Messages window (or to the terminal for batch operations) during T-Rex block initialization.
PW-19645 A 2D T-Rex domain on a propeller blade surface could not be initialized.
PW-19642 A T-Rex block with structured domains in the face was generating zero height pyramids off the quads during initialization.
PW-19626 A connector was created on a database curve, then projected onto a database surface. When the resulting projected connector was split, Bezier curves resulted containing poor quality tangents at the ends.
PW-19610 A connector could not be split in Pointwise.
PW-19596
PW-19421
A database constrained connector's distribution was set to TanH but did not display a TanH distribution of points for the provided spacing constraints.
PW-19592 The Pointwise User Manual incorrectly stated that Volume Conditions were supported for the Gridgen Generic CAE solver.

PW-19492 Splitting a database conic curve resulted in significant changes to the shapes of the two resulting curves.
PW-19489 Creating an unstructured domain on a database surface with the Create, On Database Entities command produced different numbers of bounding connectors for different versions of Pointwise.
PW-19474 A Plot3D file would import into Pointwise V17.3R1 and V17.3 R5, but it would not import into Pointwise V17.3R4.
PW-19460 The ADS CAE solver export had incorrect information being printed to the header of the export files.
PW-19429 The CMSoft-Aero CAE solver export was incorrectly using a &ldqou;3” for an eight node hex Element Type Number instead of “6”.
PW-19414 The pw::Database import Glyph command manual page contained a typo.
PW-19398 When an unstructured T-Rex domain was initialized, isotropic cells instead of anisotropic cells were generated off one section of the bounding connectors.
PW-19397 When trying to create an unstructured domain with multiple edges, the domain could only be created if the first edge's orientation was flipped.
PW-19396 In Examine, Database Associativity, a user saw white nodes instead of red/green on a Linux workstation with an ATI/AMD graphics card.
