Chorus is designed to help discern trends in large sets of data: scatter plots and line plots make tabular data much easier to interpret. But what if you wish to examine a derived variable such as an integral of a solution variable? Read this article – and watch the accompanying video – to see how you can marry Tecplot Macros with Chorus to easily create and extract such variables from a large number of CFD-analyses.

Voxel grids, in Pointwise, are fully point-matched across block boundaries. This is great since it means your solver will not have to deal with hanging nodes. However, the tradeoff is the use of pyramids to transition cell sizes. Remember that you can control the quality of pyramids, as outlined in this video.

Using C1 continuity, points out this article, is attractive to CAD modelers since it “is a much lighter data representation and yet still looks very pleasing to the eye“. CFD, in many cases, requires much more precision than that, given first-cell spacings of the order of 1 micron are not uncommon. There’s no easy way out but there are some approaches that are better than others. A common trap: when a CAD application outputs an IGES file the results are almost always sub-standard.
