“Much research remains to be done”, observe the authors of this paper on one of the many numerical problems that CAD serves up to CAE. That is as true today as it was in 2004, when that paper was published. It is well worth reading in full (go here if you prefer information in bullet points): CFD analysts will empathize with aspects such as “step size selection becomes complex and incorrect step size may lead to a critical problem“. This article is slightly less scholarly, but covers more ground.

A technique that has been around for a while poses, as noted in earlier updates (such as this one) still poses several challenges for visualization. See this article for some internals on how Tecplot approaches the problem. As the article concludes, more will be explained in subsequent post(s)!

This article presents a programmer’s view of the nuances involved in answering that seemingly simple question. Keep any eye on your CPU usage the next time you perform a time-consuming tasks on Pointwise to see how Pointwise uses the specialized tool, rather than the raw horsepower. And if you want to limit the number of threads Pointwise can use, this page of the User Manual explains how to use the parameter tbbinit.
