This Week in CFD

Meshing

Envenio shares five advantages of structured grids. #4 High Degree of Control. [For more than you probably ever want to know about Pointwise’s implementation of structured grid techniques read Quality and Control – Two Reasons Why Structured Grids Aren’t Going Away in the Mar/Apr 2013 issue of The Connector.]
CONSELF describes four mesh issues that cause inaccuracy. #3 [Lack of] Orthogonality.
Symscape advises us never to settle for faceted geometry when NURBS are available. [I personally am shocked by the number of people who simply assumed they were identical in performance.] [For a quick read on this topic, see Analytic vs. Discrete Geometry in the Sep/Oct 2012 issue of The Connector.]
Guess how many times meshing and preprocessing are mentioned in a study of FEA simulation bottlenecks.
Working with mesh data in Autodesk Inventor 2017.

Sample PowerFLOW simulation of a DENSO thermal component. See link to article below.

Exa announced a collaboration with DENSO by which the latter will compile a database of validated PowerFLOW simulations of their thermal products for their customers. See image above.

CFD is used to study the ventilation of parking garages.
Data center cooling requires a keen awareness of air movement and CEI’s EnSight can help with that. See image below.

Temperature profiles in a data center visualized in EnSight. Image from CEI. See link above.

The Call for Submissions is now open for GTC 2017, the GPU Technology Conference.
The Marine Institute of the Netherlands (MARIN) is offering a course on CFD for maritime applications this November. [The little marketer in me is wondering why these fine folks don’t use “MARINe” as the short version of their name.]
DEVELOP3D LIVE is coming to the USA for the first time on 26 September in Boston.
The 7th Beta CAE International Conference will be held in Greece on 30 May – 01 June 2017.

NASA’s PubSpace is where you’ll be able to find for free “any NASA-funded research articles in peer-reviewed journals” within one year of publication.
Why do so many women leave engineering? Regarding an internship, one female participant wrote this: “The environment was creepy, with older weirdo man engineers hitting on me all the time and a sexist infrastructure was in place that kept female interns shuffling papers…”
Analysts forecast the global cloud CFD market to grow at a compound annual growth rate of 10.73% during the period 2016-2020. [Too bad. If it was going to grow at 10.75% I was going all in.]
Phys.org reports on Peter Vincent’s PyFR CFD code being a finalist for the ACM Gordon Bell Prize.
Hot off this morning’s Twitter feed comes a report from PTC on why top companies simulate early and often. (Registration required.)
IF YOU READ ONLY ONE LINK FROM THIS POST, MAKE IT THIS ONE: Monica Schnitger gives you a 10-step primer for selecting the best CAE software. [My takeaway? “Don’t think about price; think about value.”]
Our friends at Desktop Engineering will soon be known as Digital Engineering.
CFD is not just for rockets and race cars anymore. CFD works on showers, too.

Delicious aerodynamics. Nothing more need be written. source
