Welcome to the euler2D-kfvs-Fortran2003 wiki!

Euler2D-kfvs-Fortran2003 is an Euler equations unstructured solver using kinetic flux vector splitting (KFVS) scheme. It is the successor of my Fortran 95 code euler-2D-kfvs

Some features:

  1. Cell centered finite volume method.
  2. Unstructured quadrilateral meshes.
  3. Kinetic flux vector splitting (KFVS) scheme.
  4. Written in Modern Fortran (Fortran 2003). Object-oriented programming has been implemented, mainly in the mesh reader. The solver is kept in Fortran 95, to retain its speed, which is the major advantage of the Fortran programming language.
