LS-DYNA 980: Recent Developments, Application Areas and Validation Process of the Incompressible Fluid Solver (ICFD) in LS-DYNA - Part 2

LS-DYNA version 980 will include CFD solvers for both compressible and incompressible flows. The solvers may run as standalone CFD solvers where only fluid dynamics effects are studied or they could be coupled to the solid mechanics and thermal solvers of LS-DYNA to take full advantage of their capabilities in order to solve fluid-structure interaction (FSI) problems. This paper will focus on the Incompressible CFD solver in LS-DYNA (ICFD) and will be divided in two parts. Part one will present some advanced features of the solver as well some recent developments or improvements. Part two will provide some insight on the validation process that is currently under way in order to better understand the present capabilities and state of advancement of the solvers. Several test cases and results will be presented that will highlight several main features and potential industrial application domains of the solvers. The future steps and the challenges that remain will also be discussed.
