2019-06-24Adapt refinement apps to meta-descriptorAdrian Kummerlaender
2019-06-24Slightly shift cylinder relative to finest gridAdrian Kummerlaender
This removes the "Bogus distance" warnings that are otherwise generated by `addZeroVelocityBoundary`.
2019-06-24Use Bouzidi boundary condition for refined cylinder2dAdrian Kummerlaender
2019-06-24Add refined N=20 cylinder2d example for referenceAdrian Kummerlaender
2019-06-24Improve Knudsen refinement criterion functorAdrian Kummerlaender
i.e. output cell-local quality information by default
2019-06-24Document visualization of grid refinement hierarchiesAdrian Kummerlaender
2019-06-24Initial extraction of common cylinder2d model setup functionsAdrian Kummerlaender
I am not quite happy with how this looks right now but at least both validation examples are for the most part condensed to only differ in their refinement setup. Perhaps a SchaeferTurek-specific "Solver" would further improve reproducibility?

2019-06-24Restructure refined cylinder2d example foldersAdrian Kummerlaender
2019-06-24Add cylinder2d resolution redistribution exampleAdrian Kummerlaender
i.e. cylinder2d_optimized_grid contains roughly as many grid cells as a uniformly resolved N=12 lattice but models the cylinder in more detail and is more stable.
2019-06-24Extract cylinder2d setup with refined outflowAdrian Kummerlaender
Reproducing past results for new plots is otherwise getting quite annoying.
2019-06-24Replicate SchaeferTurek 2D-2 setup in refined cylinder2dAdrian Kummerlaender
Weirdly it seems easier to get reasonably close values for the unsteady flow. Results for the steady flow seem to get worse when increasing grid resolution even in uniform grids.
2019-06-24Revamp parametrization of refined cylinder2d geometryAdrian Kummerlaender
Finally seems to stop mixing up material numbers for every other resolution I try it out with. Cylinder diameter is now actually set to 0.1m as called for by [SchaeferTurek96].
2019-06-24Add domain-restricted material number reset to SuperGeometry2DAdrian Kummerlaender
Makes it easier to exclude refined areas
2019-06-24Report pressure drop and lift of refined cylinderAdrian Kummerlaender
2019-06-24Adjust cylinder2d refinement structureAdrian Kummerlaender
Required to both increase cylinder discretization detail and fix cell count to a uniform N=9 grid.
2019-06-24Report total number of active cells in refinement hierarchyAdrian Kummerlaender
2019-06-24Move geometry print to prepareLatticeAdrian Kummerlaender
This way statistics reflect the cells disabled by refinement.
2019-06-24Manage dynamics, boundary condition memory in Grid2DAdrian Kummerlaender
Mainly to further declutter simulation and refinement setup
2019-06-24Refine cylinder2d to stay stable even at very low resolutionsAdrian Kummerlaender
Somewhat fiddled together but works as expected. Refinement areas are informed by Knudsen metric results. The key is to refine the outflow. Sadly this requires refinement-overlap-crossing boundary conditions. Interface for detailed (i.e. cell-relative) grid refinement control still has room for improvement. Mixing physical indicators and cell alignment requirements is problematic.

By deriving RefiningGrid2D from Grid2D to provide methods specific to refining subgrids.
2019-06-24Move distribution scaling factor to Coupler2DAdrian Kummerlaender
Scaling factor is specific to the refinement method implemented by the coupler.
2019-06-24Fix grid alignment of refinement areaAdrian Kummerlaender
2019-06-24Add hacky MPI support for grid refinementAdrian Kummerlaender
Works but is nowhere near anything one could consider good. Obvious issues: * More than one cuboid per grid makes it harder to determine the next lattice cell to be coupled * i.e. currently lattice positions are determined ad hoc by resolving their physical position * Coupling is not actually parallelized * All coupling lines are traversed by all processes, way to much communication * Load balancing and cuboid decomposition doesn't care about refinement * ideally refined cuboids should be computationally near their coarse _parent_ cuboids The first two isses should be fixable with a reasonable amount of work. This sadly doesn't apply in any form to the last issue.

2019-06-24Further indicatorize geometry setupAdrian Kummerlaender
Grid refinement is at its easiest when discrete materials are set using analytical - i.e. resolution independent - indicators.

Coupler construction is to be wrapped by `Grid::refine` for refinement areas that are fully inside the coarse domain.
