I am working on wave-structure interaction simulations for offshore applications using the CEL method in Abaqus. As far as I know the Eulerian analysis in Abaqus CEL method is based on the Naiver-Stokes equations similar to CFD solvers although they may use different numerical methods (FEM vs FVM). I was wondering if I would get any benefits if I switch to a CFD solver-Abaqus co-simulation other than possibly a faster solution?
