We discuss recent advances in a Computational Fluid Dynamics (CFD) framework that uses a combination of of Arbitrary Langrangian Eulerian (ALE) Dynamics and Adaptive Mesh Refinement (AMR). We describe updates and on-going work on the framework that allow for build portability on generic HPC (High Performance Computing) platforms. We also describe some of the more advanced algorithms that are available in the framework such as those which model surface tension effects in two and three dimensions. We introduce a new method for curvature and normal vector calculation in 2D, which we call the method of osculating circles. We benchmark this method and compare with other other volume of ŕuid (VOF) approaches to simulating surface tension effects. We predict how these algorithms will scale on these latest platforms such as the new Perlmutter system at NERSC which is a HPE Cray EX supercomputer with both GPU-accelerated and CPU-only nodes. We discuss the application of surface tension models to the interaction of a hydrogen droplet heated by an x-ray free electron laser with another hydrogen droplet.
