RDycore Developer Guide - Overview
This document contains information for anyone interested in helping to develop and/or maintain RDycore.
RDycore compriseѕ several related components:
- a C library that implements the actual river dynamical core model using PETSc, which provides performance portable numerical solvers, data structures like unstructured grids and vectors, and basic system-level utilities
- a Fortran library consisting of a thin wrapper around the C library, with exactly the same functionality
- standalone C and Fortran driver programs that demonstrate the capabilities of the RDycore library using RDycore's YAML input format
- various other programs and tools, including C and Fortran drivers that can evaluate rates of convergence in the solution error for RDycore when applied to specific analytical problems
Most of these components are interesting only to RDycore developers. For those
who wish to incorporate RDycore within a larger framework like E3SM,
the C and Fortran RDycore libraries (librdycore.a and librdycore_f90.a, when
built) and their corresponding header/module files (rdycore.h and rdycore.mod,
respectively) are all that is needed.
