Drawing Curves on Geometry Without a Parametric Space – New in Pointwise V18.1

simple-partDrawing curves on the geometry model is a lot more flexible in the latest Pointwise release because it can now be done when the model lacks a consistent parametric space (like a solid model comprised of a complex quilting of trimmed surfaces) or lacks a parametric space entirely (like a faceted model from an STL file).

CAD to FEA in Five Minutes

The March 2018 issue of Digital Engineering came across my desk the other day and one article in particular caught my attention. Written by Tony Abbey, the Siemens FEMAP with NX NASTRAN Overview, Part 2 article focused on meshing. In particular, Tony walked through the process of meshing a tie rod for an FEA analysis. Two things stood out while reading this article:

  1. It took 30 minutes to mesh using FEMAP.
  2. The geometry is available for download.

I thought it would be a fun exercise to attempt generating a similar mesh using Pointwise. I downloaded the geometry, imported into Pointwise, and meshed it to similar specifications in five minutes. Here’s how I did it.
