The LCA is dedicated to advancing the state-of-the-art of astrophysical simulation through the development and dissemination of community codes, and through large-scale simulations of astrophysical and cosmological systems. Our community codes include the ZEUS family of astrophysical MHD codes, and ENZO, an adaptive mesh hydrodynamic cosmological code. We also offer a new, elliptic equation, multigrid solver MGMPI. For these and other legacy codes, click on the "codes" tab above. Members and collaborators of the LCA apply ZEUS and ENZO to a wide variety of fluid dynamical probelms in astrophysics and cosmology. These are overviewed on the "projects" page. A new LCA initiative is the creation of a browseable data archive.
