Multilevel Solvers for High Resolution Electric Field Calculations
18 Aug 2015 | | Contributor(s):: Andrew Reisner
High fidelity electric field calculations are a critical component in plasma simulations. In this this talk we consider the problem of a dielectric barrier discharge (DBD) wherein the electric field is calculated to support a compressible flow, thus requiring a highly efficient global solve. The...
