This repository contains two plugins that provide extra functionality to the coolfluid 3 project.

• DCM: Discontinuous Collocation Methods
• SDM: Spectral Difference Method

Plugin DCM

Discontinuous Collocation Methods acts as a library of building blocks for a family of discontinuous collocation methods such as the spectral difference method, discontinuous galerkin method, ...

Provided in this plugin are e.g. libraries

• core: Metrics (interpolation, etc), element connectivities, ...
• equations: Advection Diffusion, Euler, Linearized Euler, Navier-Stokes
• solvers: classic Runge-Kutta, Low-storage Runge-Kutta

Plugin SDM

Spectral Difference Method for solving Partial Differential Equations

Provided in this plugin are, using building blocks from the DCM plugin:

• Computation of convective and diffusive terms using the Spectral Difference method. Diffusive terms are computed using the Second approach of Bassi-Rebay (BR2)
• Low-storage explicit Runge-Kutta schemes, specifically optimised for the SDM

###Installation: ###

• Create a plugins directory if not existing, and clone this repository inside:

mkdir -p $PLUGIN_DIR
cd $PLUGIN_DIR
git clone https://github.com/coolfluid/dcm.git $PLUGIN_DIR/dcm_plugins

• Rerun cmake in the coolfluid3 build directory:

cd $CF3_BUILD_DIR
cmake .  -DCF3_PLUGIN_DIRS=$PLUGIN_DIR
