Abstract:

EMPulse is a comprehensive and modern 3-D simulation code for electromagnetic pulse EMP formation and propagation studies, being developed at LLNL under a Laboratory Directed R and D LDRD initiative that was launched in the fall of 2014. EMPulse builds upon the open-source Warp particle-in-cell code framework which was developed by members of this team and collaborators at other institutions. The goal of this endeavor is a new tool, using methods different from those in common use, and enabling the detailed and self-consistent study of multi-dimensional effects in geometries that have typically been treated only approximately. Here we describe the underlying Warp framework and its capabilities the models that have been or are being newly developed and incorporated into EMPulse, tests of these models, and number of approaches to increased computational efficiency that we are studying.
