Blockstructured Adaptive Mesh Refinement in object-oriented C++

3D Euler equations - Forward facing step Problem description       Results:   3 Levels

This example has been inspired by the planar flow against a rectangular step (see forward facing step).

Initial / Boundary Conditions

Numerical Simulation

• Three-dimensional Euler-equations for an ideal gas (Air with gamma=1.4)
• Dimensional splitting, Van Leer solver, MUSCL variable reconstruction with Van Albada limiter
• Calculation with CFL-No. 0.95 to time t=4.0
• AMR-computation with a coarse grid of 60x20x40 cells

    3 grid levels:

• Calculation of 352 time steps
• 2 levels with refinement factor 2 are used.
• Finest level corresponds to 240x80x160 grid (3.07 M cells)
