We propose a hybrid method that uses a Poisson solve on a coarse grid to enforce a divergence free velocity field, followed by a local density correction of the particles. This avoids typical grid artifacts and maintains the Lagrangian nature of SPH by directly transferring pressures onto particles. Our method can be easily integrated with existing SPH techniques such as the incompressible PCISPH method as well as weakly compressible SPH by adding an additional force term. We show that this hybrid method accelerates convergence towards uniform density and permits a significantly larger time step compared to earlier approaches while producing similar results. We demonstrate our approach in a variety of scenarios with significant pressure gradients such as splashing liquids.","lang":"eng"}],"department":[{"_id":"ChWo"}],"day":"05","type":"conference","file":[{"relation":"main_file","checksum":"6579d27709946e0eefbfa60a456b4913","content_type":"application/pdf","file_name":"IST-2016-598-v1+1_HybridSPH_Preprint.pdf","access_level":"open_access","creator":"system","date_updated":"2020-07-14T12:46:06Z","file_id":"4769","file_size":2536216,"date_created":"2018-12-12T10:09:44Z"}],"date_updated":"2023-02-23T11:21:05Z","month":"08"}
