Abstract Text:
The Interfacing Group of the Plasma Science and Innovation Center (PSI-Center http://www.psicenter.org) facilitates simulations of collaborating Emerging Concept (EC) experiments. This includes helping set up experiments for new simulations, assisting in comparison of simulations with experimental data, acquiring and disseminating information about simulations to PSI-Center computational groups, and acting as a conduit of information between experiments. Present collaborating experiments include the Bellan Plasma Group (Cal-Tech), FRX-L (Los Alamos National Laboratory), HIT-SI (Univ of Wash), MBX (Univ of Texas-Austin), PHD (Univ of Wash), SSPX (Lawrence Livermore National Laboratory), SSX (Swarthmore College), TCS (Univ of Wash), and ZaP (Univ of Wash). The Interfacing Group also administers a local development computational cluster, a 16-processor (1.5 GHz Intel Itamium2 CPUs w/6MB L3 cache) SGI Altix 350 cluster with 32 GB shared memory, and an associated firewalled network.

PSI-Center 3-D resistive MHD codes include NIMROD (http://www.nimrodteam.org) and MH4D. NIMROD has been modified to include generalized applied voltage boundary conditions and external coils. Re-entrant grids for SSX and MBX have been successfully generated, allowing easier gridding of the other collaborating experiments. Each collaborating institution has been contacted, and plans for progress have been laid out, starting with direct gridding and running in NIMROD (SSX and MBX), 2D (MOQUI) and initial 3D simulations of FRCs (FRX-L, PHD, and TCS), modification of MH4D (HIT-SI, ZaP), and improved access to simulation data for visualization and comparison to experiments (Bellan Group and SSPX). Initial results, improved numerical diagnostics, and data visualization for collaborating experiments will be presented.
