Announcements Pointwise will host a free hour-long webinar at 11 a.m. CDT on 2 May on the topic How T-Rex Unstructured Meshing Aids Transonic Aircraft Drag Reduction.

T-Rex, Pointwise’s anisotropic tetrahedral extrusion method, is a robust and highly automated way of creating unstructured viscous meshes on complex geometries that reduces the effort required to generate meshes on which drag can be predicted accurately.

Reducing the aerodynamic drag of an aircraft is important because it produces a proportional reduction in fuel consumption.

“Predicting drag with computational fluid dynamics (CFD) can be very challenging, particularly for modern commercial aircraft that fly at transonic speeds,” said Dr. Chris Sideroff, Pointwise sales engineer. “For the complex geometries encountered on these aircraft, creating meshes that resolve flow structures to achieve the necessary accuracy can be tedious and error prone. That’s why Pointwise’s T-Rex method is designed to automate the process, making the engineer’s job easier, faster and the results more reliable.”

The webinar will demonstrate how to

  • Utilize 2D T-Rex to more efficiently resolve surface curvature

  • Diagonalize trailing edge surfaces for more consistent grid point distribution

  • Tune T-Rex parameters to handle difficult regions, such as corners, high curvature and transitions

  • Reduce time spent setting up T-Rex meshes using its top-down approach

  • Convert boundary layer tetrahedra into triangular prisms

The webinar will be presented by Dr. Sideroff and Travis Carrigan, Pointwise sales engineer.

Dr. Sideroff joined Pointwise in September 2007 after working as a petroleum engineer for the NATCO Group, a CAD engineer for ARV Development, and a computer technician for Harddata Ltd. Dr. Sideroff earned both a B.S. and M.S. in mechanical engineering from the University of Alberta in 2000 and 2003. He earned a Ph.D. in mechanical engineering from Syracuse University in 2009.

Mr. Carrigan joined Pointwise as a technical sales engineer after completing his M.S. in aerospace engineering at the University of Texas at Arlington in May 2011. He interned at Pointwise beginning May 2008, producing demonstration and application videos and working in technical support, doing grid projects and quality assurance testing. He received his B.S. in aerospace engineering in 2009 from UTA.
