Discontinuous Collocation Methods

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
