New Features in Pointwise V18

Pointwise V18 has many new features related to creating and working with hybrid grids. In this session, we will demonstrate how and why to use these features. You will get the chance to try them yourself in hands-on exercises:

  • Easily build unstructured quad-dominant surface meshes containing quadrilateral cells and some triangles to get good surface resolution with a reduced number
    of cells.
  • Extrude unstructured hexahedra from quad-dominant, structured, and even triangular surface meshes.
  • Examine mesh quality of agglomerated T-Rex (anisotropic tetrahedral extrusion) meshes (tetrahedra, pyramids, prisms, and hexahedra)
  • Control mesh size inside tetrahedral blocks using Draw Shapes to define refinement regions and Grid Sources to set cell sizes in those regions
  • Learn about many other productivity enhancers, including:
    • Unstructured Blocks
    • New/Updated Examine Functions
    • Entity-linked Messages
    • Auto-Hide Domains with BCs
    • Improved Shell Support
    • Improved File I/O for CGNS, Tecplot, and TAU

Mastering Geometry Cleanup Tasks in Pointwise

Importing and manipulating CAD geometry in Pointwise to make it more suitable for meshing is not always well understood, and it sometimes may seem coincidental when you finally assemble your surfaces into a solid model. This course aims to remove any ambiguities involving the suite of CAD tools available in Pointwise. Participants should come away with a better understanding of the geometry creation and editing utilities available to them, how to better anticipate their behavior, and how to identify situations that can influence meshing decisions.

This session uses complex, practical CAD examples to demonstrate how to:

  • Leverage the updated Import Database panel in Pointwise V18, and let Pointwise detect suitable tolerances automatically for you
  • Visualize model tolerances using new Examine metrics and discover how they can influence meshing decisions
  • Identify and heal gaps in geometry to expedite watertight model assembly prior to meshing
  • Apply strategies for identifying and recreating missing and untrimmed surfaces
  • Distinguish whether your imported geometry is ready for meshing and discover why some of these issues are not apparent in your CAD application
