Warp VND

The Warp code is a particle-in-cell (PIC) framework designed to model high-current particle beams and plasmas and to support a wide variety of integrated physics models. Warp VND is a Sirepo-based prototype for simulating vacuum nanoelectronic devices. The Sirepo applications supports a subset of these capabilities in an easy-to-use GUI. The code is primarily supported by David Grote, Jean-Luc Vay, Remi Lehe and other colleagues at Lawrence Berkeley National Laboratory and Lawrence Livermore National Laboratory. Warp is part of the Berkeley Lab Accelerator Simulation Toolkit.
