Improved mapping and reconstruction of free surface after AMR The simulations produced similar results which can be seen by the picture. In the AMR case the mesh size was much smaller than that of the static case. A dishwasher is run with and without the AMR. The picture below shows the results from a comparison for an industrial case. This means that the film will not be affected at all, instead putting the refinement on the bulk section of the mesh, where it is most often better needed. The way this is performed now is that the first cell layer closest to the wall is shielded from the AMR. But now these approaches can be used together. Before where fluid film was required together with VOF to solve the relevant physics, the user was forces to use a static mesh. VOF is preferably used with free-surface AMR to keep the total cell count at a reasonable level. Often the Fluid film is used together with VOF (Volume of Fluid). This now invites the hybrid multiphase approach to many industrial applications not previously considered or that was too expensive to solve. It is now possible to combine fluid film with Adaptive Mesh Refinement (AMR). This time we will focus mainly on multiphase features, both those in the Eulerian and Langrangian frameworks. This version of the software was released last week and contains several improvements worth highlighting. In this blog post we will keep looking at the highlights of the news for Simcenter STAR-CCM+ version 2021.2.
