Blockstructured Adaptive Mesh Refinement in object-oriented C++
2D Euler equations - Shock-Bubble interactionProblem description Results: 2 Levels 3 Levels
A planar shock-wave hits a spere of lower density. Cylindrical symmetry is exploited by employing the two-dimensional cartesian Euler equations and incorporating additional terms by a fractional step method. This example demonstrates the usage of source terms and auxilary arrays.
Initial / Boundary Conditions
- Two-dimensional Euler-equations for an ideal gas (Air with gamma=1.4)
