RDycore User Guide - Overview
RDycore's primary purpose is to provide E3SM with the capability to model coastal compound flooding. Accordingly, it has been constructed as a performance-portable library that makes efficient use of DOE's leadership-class computing facilities and is invoked by E3SM Fortran code.
Aside from the library, RDycore provides standalone drivers that can help you test and evaluate the model's capabilities:
-
standalone C and Fortran driver programs for running uncoupled flood simulations given appropriate initial and boundary conditions, source terms, etc.
-
standalone C and Fortran verification programs that use the method of manufactured solutions (MMS) to evaluate the stability and accuracy of the underlying numerical methods by computing error norms of simulation results measured against analytical solutions. These MMS programs can also compute convergence rates, which are useful for identifying algorithmic and programming errors. Because these programs are more technical and used to identify defects, they are described in the Developer Guide.
This guide also describes these standalone programs and their features. It also explains how we integrate RDycore to E3SM to perform coupled simulations of compound flooding.
