This software uses Nodal Discontinuous Galerkin Finite Element Methods (NDG-FEM) to solve advection, advection-diffusion and various hydraulic problems in one, two and three dimension. The software is written in Matlab and C languages and uses OpenMP for parallelization. The simulation results can be exported in the nc format and vtk format, while the visualization is also supported by Matlab.
Part of the software codes are written in C Mex functions. Before the users start their simulation, these C functions need to be compiled first.
- Install TDM-GCC software, including OpenMP package
- configure TDM-GCC as the default compiler for Matlab
- run script
NdgSetup.m
- Install Intel C compiler
- configure
iccas the default compiler for Matlab - run script
NdgSetup.m
Use following commands to run a two-dimensional advection probelm
adv = ConstAdvUniformMesh2d( 1, 60, enumStdCellType.Quad );
adv.matSolve;
pos = makeNdgPostProcessFromNdgPhys( adv );
pos.drawResult( 1, 1, 0 )
This software is inspired by Nodal Discontinuous Galerkin Methods Algorithms, Analysis, and Applications Texts in Applied Mathematics (Hesthaven and Tim Warburton, 2008), please refer to NodalDG for more details.
