Center for Extended MHD Modeling (CEMM)

a SciDAC activity based on extensions and applications of the NIMROD and M3D codes


The Center for Extended Magnetohydrodynamic Modeling will enable a realistic assessment of the mechanisms leading to disruptive and other stability limits in the present and next generation of fusion devices. The main work involves extending and improving the realism of the leading 3D nonlinear magneto-fluid based models of hot, magnetized fusion plasmas, increasing their efficiency, and using this improved capability to pioneer new tera-scale simulations of unprecedented realism and resolution. This will provide new insights into some of the most critical and complex phenomena in plasma and fusion science. The proposed work builds on the established research teams that have developed the NIMROD and M3D codes. Activities are proposed in the following areas: Code Development-- improving the computational performance, implementing extended MHD models, and validation of the numerical algorithms; Model Development-- refining numerically tractable physical models for extended MHD (XMHD) and testing their efficacy; Visualization and Data Management-- providing visualization and data handling capabilities; Computer Science Enabling Technologies (CSET) -- which consists of several supporting computer science projects; Code Support--consisting of disseminating the code capability to the community, and supporting the developing user base; Applications and Validation-- applying and validating the underlying models through cross-code and experimental comparisons
