The Center for Computational Sciences and Engineering (CCSE) develops and applies advanced
computational methodologies to solve large-scale scientific and engineering problems arising in the Department of
Energy (DOE) mission areas involving energy, environment, and industrial technology. The primary focus
of CCSE researchers is on designing algorithms for multiscale, multiphysics problems described by
nonlinear systems of partial differential equations, and in developing implementations of algorithms
that target current and next-generation massively parallel computational architectures. Sample
application areas include combustion, porous media flow, fluctuating hydrodynamics,
atmospheric modeling, cosmology and astrophysics. CCSE researchers work collaboratively with application
scientists to develop state-of-the-art solution methodologies in these fields.

CCSE is also the home of **AMReX**, a software framework for massively parallel block-structured
adaptive mesh refinement (AMR) codes. AMReX is used for the development of new algorithms
and is the basis for many mature AMR applications.
