cl1de stands for "Conservation Law 1D Explicit".
As its name suggests, it is used to solve conservation laws in 1D,
using explicit time integration. Currently the following
conservation laws are supported:
- Variable-area compressible, inviscid Euler equations
The following conservation laws are also planned:
- 2-phase, variable-area, compressible, inviscid Euler equations
- Shallow water equations
Planned spatial discretization schemes include various flavors of the following families:
- Finite volume
- Discontinuous Galerkin finite element
Temporal discretizations include the following:
- Explicit TVD Runge-Kutta (AKA SSPRK) methods of orders 1, 2, and 3
It is written in C++ with minimal external dependencies.
Compilation is performed using make. An executable is created
per problem:
make <problem_name>
where <problem_name> is the name of the problem. Each problem
resides in a first-level sub-directory of the problems directory,
and the associated main C++ file is named as <problem_name.cpp>.
make <problem_name> creates the executable problems/<problem_name>/run.
The executable is run with the name of an input file as an argument:
./run <input_file>
The output is the file output.csv, which contains the final solution
vectors for the associated conservation law.
