Importing an arbitrary STL surface for post-processing in CFD VIEW

When using the Arbitrary-Cut operator, you have the option to directly import an external surface in STL format into the model. This option, which was first made available in V2013.4, underwent significant performance improvements in V2014.0. This option provides the ability to plot data and process information on any arbitrarily shaped surface. The import process involves reading the STL file and computing the intersections between this surface and the model’s volume cells. Results on the imported surface are interpolated from the intersected volume cells and are independent of the surface mesh size of the STL as long as the surface is properly represented.
