The latest release of Caedium (v5.1.3) from Symscape has a new Helix tool for your Computational Fluid Dynamics (CFD) simulations and improved mesh element size control. Using the new Helix tool you can create cylindrical or conical helices for your CFD simulations. For example, combined with the improved Sweep tool you can now sweep an edge along a helix to produce a strake for a chimney. With the improved mesh element sizing for the Accuracy tool you can now be confident that the mesh size is locally bounded around the geometry with the applied mesh size constraint. This release also includes a number of critical bug fixes.
