Implement in class OutputMesh adaptive refinement according to scalar field
prerequisite: #608
##### How to refine - simplex refinement ?
- find middle node of every edge; connect the middle nodes; c…

Our assumption that data in `ParArray#D`s is initialized to 0 does not hold for simulations with adaptive mesh refinement!
That may lead to very subtle bugs in the initial conditions.
When (adaptive…

Velocity oscillations occur if we use a mesh with hanging nodes (refined mesh, but not necessarily changing over time) in combination with mesh deformation due to moving model boundaries (ALE formulat…

We have found a parameter called "IADAPT" in the parameter.f90 file. By searching a bit, we have seen that probably it is used for adaptive mesh refinement technique. but in your paper, there is no me…

### Describe the bug
When I plot the mesh (alternatively Pseudocolor->density), there is a blank region around the coarse-fine boundary of the adaptive refinement mesh. The plot looks fine if I use t…

### Is your feature request related to a problem?
In cases where original cell ids are used, it would be handy to have a toggle that shows all the cells for debugging and general understanding

Here I am collecting some ideas for an enhancement of the library. The features below can mainly be implemented in the `Problem` because all types of problems would benefit from them.

We have an application requires to store quantities defined on element sides. These quantities are discontinuous on the two side of the sides and can be discontinuous on the node (2D) or edge (3D). It…
