CG: A Suite of Composite Grid PDE Solvers - Source Code Documentation

Introduction

This document contains the CG source code documentation. CG is a suite of partial differential equation (PDE) solvers for composite overlapping grids. CG is built upon the Overture software framework. CG is written in C++ at the high level and uses Fortran kernels.

Available PDE Solvers

Here is a summary of the various solvers in the CG suite.

• Cgad : advection diffusion solver.
• Cgasf : all-speed flow solver (not mature).
• Cgcns : compressible flow solver.
• Cgins : incompressible flow solver.
• Cgsm : solid mechanics solver.
• Cgmx (Maxwell) : Maxwell's equation solver (electro-magnetics).
• Cgmp : multi-physics, multi-domain solver.
