ISITEK is a 2D unstructured discontinuous galerkin PDE solver
Non-linear PDEs and boundary conditions are specified at runtime in the input file
PDEs are solved for a number of outer iterations in a coupled manner using newton (or newton-like) inner iterations
The spatial order of accuracy is arbitrary and specified at runtime
Fluxes can be calculated via an interpolation method or a weighted method
- The interpolated method is stable for higher order fluxes occuring in diffusive or elliptic problems
- The weighted method facilitates averaged or upwind fluxes
A slope limiter is employed for non-smooth problems

Use the install script in the third party directory to obtain and build the necessary linear algebra packages, GotoBLAS and UMFPACK

cd thirdparty
./install.sh

Alternatively, edit the makefile to reference intel MKL libraries

Back in the root directory, build the solver

cd ..
make

Move into one of the example directories

cd cavity

Run the program with the input file as the sole argument

../isitek cavity.INS.input

Paraview can then be used to view the resulting vtu files
