• Complicated boundary conditions
• Difference methods
• Discontinuous finite element method
• Double Mach reflection of a strong shock
• Hydrodynamic equations
• Third order accuracy
• Triangular mesh
• Two dimensional domain
• Wind tunnel with a step

The discontinuous finite element method with first, second and third order accuracy on triangular meshes on two-dimensional domain is applied to simulate hydrodynamic equations. The calculation results are compared with those from difference methods. It is reckoned that the discontinuous finite element method has advantages in solving hydrodynamic problems with complicated boundary conditions or a domain with a complicated boundary.
