The effect of numerics on the simulation quality and convergence time.

three different apollo capsule should be tested:
* normal
* with retro booster off
* with retro booster on

find optimal air gap to maximise heat convection per Volume

try different gradient schemes:
* linear
* leastSquares
*fourth
try different flux schemes
* tadmor
* kurganov

A diamond shaped profile in supersonic speed / transsonic regime is tested with different boundary conditions.

in this project i test different solver and solver settings and compare them to analytical solution of sod's shock tube

This simple benchmark is a good test to show how depend the execution time on mesh size and processor number.

This case contains six meshes, with cell sizes from a half million to 8 million.
Also every mesh will be benchmarked with all combinations of cpu counts.
the mesh decomposition algorithm is scotch, it tries to minimize the faces between the processors. (the best algorithm for speed up )
In the end there will be 36 results to determine the speedup and give an estimation of how much processors are needed for a desired mesh.

FYI: difference between executionTime and clockTime
clockTime mean how long it took to complete the task, inclusive interconnection between processors, operating system need also some cpu resources and other tasks...
executionTime mean only all the time the simulation used on all processors

Effect of Boundary Layers and possible improvements
try to reduce numbers of cells for faster computation

This project shows an example on how certain phenomena involved in heat exchangers can be simulated with SimScale.

This Project is Simulating the Bloodhound SSC supersonic land vehicle at 1050mph.
