Thanks Rob. Over the past few weeks I managed to get better MPM model results using a smaller time step. I am testing MPM models with hexahedral meshes at the moment and the results are also good. In relation to simulating a dropping object using moving meshes, is there literature or any tutorial with advice on setting up 3D dynamic mesh 6dof simulations that don’t use the VOF multiphase model and involve geometries moving (ideally falling) in a viscous fluid? My interest is primarily in relation to hexahedral meshes, and so far I understand that hexahedral meshes can only be layered and/or smoothed, but not remeshed. Thanks for your time.
