ColiseumPrincipal Investigator: Lubos BriedaCOLISEUM is a software developped by the Air Force Research Labs, Edwards AFB, in cooperation with Virginia Tech and MIT. COLISEUM is a flexible, usable, 3-D plasma interaction modeling system that is being developed to predict the interaction of electric propulsion plumes with surfaces. COLISEUM allows users to easily define complicated 3-D geometries using off-the-shelf CAD software, then select from a set of plasma expansion models of varying fidelities and run-times to perform the solution. With this system, low fidelity models can be used to verify the geometry and boundary conditions, and to obtain first-order predictions. Then, higher fidelity models can be used to obtain the most accurate predictions available, after higher computation times. Virginia Tech's Computational Advanced Propulsion Lab is responsible for providing COLISEUM with a full Particle-in-Cell package. This package contains several field solvers such as DADI, IFE(Immersed Finite Element, developped at Virginia Tech) and other solvers are in development. To increase the convergence as well as the accuracy of the solvers a multigrid support has been added to COLISEUM, thus finer meshes can be added around objects where an in depth study is needed. Currently a full parallel version of the code is being written. This version will allow COLISEUM to run larger simulations on parallel computers. |
