Sometimes referred to as Response Surface Models or Meta-Models, surrogate models are an elegant way out of the thicket of data-overload. Tecplot Chorus offers you an easy way to construct them for – as with anything else in Tecplot – pretty much any data you have available. Read this article for a quick tutorial that may change the way you approach multiple solution sets.

Multi-grid methods are a well recognised option in many flow solvers. Somewhat less widely appreciated is their use in smoothing grids. See this report for some early background, and view this short video to see how Pointwise uses these to great effect with 2D grids, and this one for 3D grids.

Many supply-chains require CAD model-authentication, comparing an original model and the derived model. This can be useful for internal use too: for example, if you’ve spent significant estimation-time on a part only to have the author make a change.

But what determines the significance of changes? This is where dual profiles come into their own: specify different “inside” and “outside” tolerances to zero in on changes that you deem significant. View this short video for an overview.
