allow to change the append and compress argument of vtk_grid in writeVTK

1

see https://juliavtk.github.io/WriteVTK.jl/dev/grids/syntax/ for the purpose of append and compress and Issue https://github.com/JuliaVTK/WriteVTK.jl/issues/136 where these somehow lead to corrupted files that cannot be opened with some paraview versions on some architectures...

if the subgrid dimension is one, the subgrid method sorts the coordinates of the resulting grid without permuting the CellNodes, BFaceNodes etc. This may lead to unexpected behaviour in situations...

RefinementRules to merge uniform_refine, barycentric_refine and spit_into functions

1

Merges refine_uniform, refine_barycentric and split_into function into one function based on new RefinementRule type, also adding new uniform refinement types of triangles suitable for quadratic and cubic Lagrange interpolations.

better fix for negative cell volumes in tensor grid simplexgrid constructor

1

It was observed that the old tensor grid simplexgrid constructor can lead to meshes with negative cell volumes which can confuse solvers and CellFinder. The current quick fix (https://github.com/j-fu/ExtendableGrids.jl/commit/f9d47ae0d297d379a7e1838727f6ad303e390274) corrects...

discontinuous cellwise plots

3

cellwise switch is now handled in 2d Makie scalarplot (isolines are switched off for now, though)

Garbage collection of unused grid component

4

Meanwhile the components dictionary in an ExtendableGrid accumulates all kind of adjacency and may contain redundant information that can be recalculated again from the main adjacencies (like NodeCells, but also...

EdgeParents are needed for higher order finite elements on subgrids. I guess this can be handled very similar to FaceParents in instantiation of FaceNodes.
