Verification and validation repository for QGD/Hybrid solvers

The primary objective of the repository is to gather and store updated verification and validation problems showing strengths and weakneses of the aforementioned computational complexes.

Available cases

Next cases are available (uploaded to the repository):

• a Sod's shock 1D tube;
• a 2-rarefaction 1D problem;
• a shock with high pressure ratio 1D problem;
• a two shocks problem;
• a two gases diffusion case;
• a forward step;
• a Sod's problem for two gases;
• a 1D reactive tube;
• a Re=100 bakward facing step;
• a planar acoustic wave propagation;
• a converging-diverging nozzle;
• a stationary contact discontinuity problem;
• a moving contact discontinuity problem.

Cases with automated verification procedure

• the Sod's shock tube;
• the 1D reactive tube;
• the stationary contact discontinuity problem;
• the moving contact discontinuity problem.

The structure of the repository

The structure of the repository is next.

1. On the first level go folders with titles of problems.
2. On the second level inside a problem folder we keep folders:
   • for reference data (reference/);
   • for literature (docs/);
   • for results of comparison (comparison/) with reference data and between different solvers;
   • for cases computed using different solvers (e.g., QGDFoam/, pimpleCentralFoam/, rhoCentralFoam/, etc);
   • for common data shared by different solvers (common/) cases.
3. On the third level, inside the solver folders we keep computational cases in folders with names specifying the mesh density (e.g., 10CPL, 20CPL, etc).

The wish list of cases to check is maintained using the issues section of the repository with all neccesary links to reference data and description of problems.
