Researchers at RWTH Aachen University are studying fluid-structure interaction on wind turbine rotor blades to develop strategies to increase their life expectancy and reliability. They use Pointwise's T-Rex for control over the meshing process.
Grid quality affects the accuracy and convergence of CFD solutions; however, it is difficult to define exactly what makes a good mesh for a given problem. Pointwise senior engineer John Rhoads shows some results for numerical errors on a basic advection problem to provide some insight.
At the Pointwise User Group Meeting 2014 in Anaheim, CA, attendees from around the world enjoyed a variety of technical presentations, training on the latest capabilities of Pointwise, a glimpse of our product development plans, and a celebration of Pointwise's 20th anniversary.

OpenVSP is an open source, parametric modeler used to quickly capture design intent so geometry information is easily provided in the appropriate form for various uses, including CFD. Therefore, several approaches were explored by which OpenVSP and Pointwise could be integrated to automate the volume meshing process for CFD.
