Pointwise Training Includes Overset, New Tools and Techniques

Training classes at the Pointwise User Group Meeting 2014 will include a mix of overset meshing, new features in Pointwise, instruction in quickly making layers of high-quality unstructured hexahedral cells using T-Rex (anisotropic tetrahedral extrusion) and a special short course, Advanced Structured Gridding. Training will begin at 8:30 a.m. and last throughout the day on 29 October. The user group meeting will be in Anaheim, California, and will include a celebration of Pointwise's 20th anniversary.

Overset Meshing Introduction

Overset Meshing Introduction outlines the concepts of overset meshing and the basic process of overset grid assembly using Pointwise. New, hands-on overset meshing tutorials will be provided.

  • Advantages of overset meshing
  • Overset terminology
  • Topology considerations
  • Do's and don'ts

Overset Assembly and Diagnostic Tools

After learning the basic concepts of overset meshing, there will be a detailed discussion of meshing tools during the Overset Assembly and Diagnostic Tools session, including the advanced visualization capability offered by Pointwise for viewing all of the characteristics of an assembled overset grid system, such as fringe points, orphans, etc.

  • Software requirements
  • Assembly attributes
  • Local and remote assembly
  • Possible assembly errors
  • Examine overset tools and options

Pointwise's Latest New Features

The afternoon session will begin with instruction in Pointwise's Latest New Features, including many new productivity enhancements. There will be demonstrations of these features and opportunities to try them in hands-on exercises.

  • Automated unstructured block assembly
  • Align View to Surface
  • Improved and updated CAD file readers
  • Drawing Guide
  • Enhanced connector projections
  • Save Selection As
  • Save Environment
  • Mirror on Export
  • New and upgraded CAE solvers
  • Shading Light Source Control

Prism and Hexahedral T-Rex Meshing

Pointwise's T-Rex technique has been extended to quickly make layers of high-quality unstructured hexahedral cells with automatic adjacent layer collision detection, quality checking, and anisotropic-to-isotropic transitioning. The Prism and Hexahedral T-Rex Meshing class will explore how to create T-Rex boundary layer meshes containing both prisms and hexahedral cells and how to match T-Rex blocks with adjacent structured blocks to form a truly hybrid mesh.

  • Creating structured domains for T-Rex
  • Using structured Match domains
  • Applying optimal T-Rex settings
  • Combining T-Rex cells into prisms and hexahedra

Special Short Course: Advanced Structured Gridding

Hexahedral structured grids are widely considered optimal for precision CFD calculations, but realistic geometries often contain configurations not conducive to easily-visualized, straightforward multi-block approaches. The Advanced Structured Gridding short course will highlight advanced structured gridding techniques for quickly conceptualizing and building complex structured grids.

  • Create structured topologies for non-rectangular shapes
  • Generate boundary layer-resolved grids using hyperbolic extrusion
  • Improve cell quality using the elliptic domain and block solvers
  • Create structured surface grids well suited for use with T-Rex (anisotropic textrahedral extrusion).

The short course topic was chosen by popular vote.
