This Week in CFD

This week’s CFD news includes not one but two articles about smells and smelling. We should take it as a good sign that this summer’s USNCCM still plans to be a hybrid event with some folks in-person which would be a great step toward conference normalcy. There’s a white paper on geometry model preparation that we’d like you to have a look at, a couple job openings, and signs of robust business in the CAE market which is great. Shown here is a CFD simulation of shallow, free-surface flows from a summary article about the 22nd Australasian Fluid Mechanics Conference.

APPLICATION OF THE WEEK. Pressure distribution and flow dynamics in a nasal airway using a scale resolving simulation using ANSYS Fluent. Originally seen on the Leap Australia blog. [And congrats for not using a sickly green color map for this particular simulation which, while perhaps appropriate, would’ve been gross.]

CFD for…

Business & Jobs

  • Siemens Digital Industries Software has an opening for a STAR-CCM+ Product Manager, someone with both CFD and HPC interests and experience. See more at this LinkedIn post.
  • For the last calendar quarter of 2020, PTC’s revenue increased 20% to $429 million. As reported by Monica Schnitger, this growth may be attributed to PTC’s inclusion of ANSYS CAE, Frustrum’s generative design, and Arena for PLM.
  • Dassault Systemes also had a good Q4 with revenue up 18.4% to €1,219 million.
  • The folks who invested in Google in 1999 have now invested in Physna, a 3D search engine said to be like a GitHub/Google mashup.
  • TransMagic and ProtoTech are working together on CAD translators that bridge the AEC and MCAD industries.
  • Pointwise seeks an Applications Engineer for our Engineering Services team. (Must love meshing!)
  • Coreform was awarded an SBIR contract for simulation of complex 3D printed parts.

A Grid That Looks Back at You

From the Tate’s collection comes Victor Vasarely’s Supernovae. I’m not going to blather on about it and instead let you enjoy its ocular frisson. It’s hard to look away.
