| virtual void | node_update (const bool &update_all_solid_nodes=false) |
| Update nodal positions in response to changes in the domain shape. Uses the FiniteElement::get_x(...) function for FiniteElements and doesn't do anything for other element types. If a MacroElement pointer has been set for a FiniteElement, the MacroElement representation is used to update the nodal positions; if not get_x(...) uses the FE interpolation and thus leaves the nodal positions unchanged. Virtual, so it can be overloaded by specific meshes, such as AlgebraicMeshes or SpineMeshes. Generally, this function updates the position of all nodes in response to changes in the boundary position. However, we ignore all SolidNodes since their position is computed as part of the solution – unless the bool flag is set to true.

| int | face_index_at_boundary (const unsigned &b, const unsigned &e) const |

Adapt mesh: Refine elements whose error is lager than err_max and (try to) unrefine those whose error is smaller than err_min.
Do adaptive refinement for mesh.
- Pass Vector of error estimates for all elements.
- Refine those whose errors exceeds the threshold
- (Try to) unrefine those whose errors is less than threshold (only possible if the three brothers also want to be unrefined, of course.)
- Update the nodal positions in the whole lot
- Store # of refined/unrefined elements.
- Doc refinement process (if required)

|
virtual |
Perform the actual tree-based mesh adaptation, documenting the progress in the directory specified in DocInfo object.
Adapt mesh, which exists in two representations, namely as:
- a FE mesh
- a forest of Oc or QuadTrees
Refinement/derefinement process is documented (in tecplot-able form) if requested.
Procedure:
- Loop over all elements and do the refinement for those who want to be refined. Note: Refinement/splitting only allocates elements but doesn't build them.
- Build the new elements (i.e. give them nodes (create new ones where necessary), assign boundary conditions, and add nodes to mesh and mesh boundaries.
- For all nodes that were hanging on the previous mesh (and are still marked as such), fill in their nodal values (consistent with the current hanging node scheme) to make sure they are fully functional, should they have become non-hanging during the mesh-adaptation. Then mark the nodes as non-hanging.
- Unrefine selected elements (which may cause nodes to be re-built).
- Add the new elements to the mesh (by completely overwriting the old Vector of elements).
- Delete any nodes that have become obsolete.
- Mark up hanging nodes and setup hanging node scheme (incl. recursive cleanup for hanging nodes that depend on other hanging nodes).
- Adjust position of hanging nodes to make sure their position is consistent with the FE-based represenetation of their larger neighbours.
- run a quick self-test on the neighbour finding scheme and check the integrity of the elements (if PARANOID)
- doc hanging node status, boundary conditions, neighbour scheme if requested.
After adaptation, all nodes (whether new or old) have up-to-date current and previous values.
If refinement process is being documented, the following information is documented:
- The files
- "neighbours.dat"
- "all_nodes.dat"
- "new_nodes.dat"
- "hang_nodes_*.dat" where the * denotes a direction (n,s,e,w) in 2D or (r,l,u,d,f,b) in 3D
can be viewed with
- QHangingNodes.mcr
- The file
- "hangnodes_withmasters.dat"
can be viewed with
- QHangingNodesWithMasters.mcr
to check the hanging node status.
- The neighbour status of the elements is documented in
- "neighbours.dat"
and can be viewed with
- QuadTreeNeighbours.mcr
Update the boundary element info – this can be a costly procedure and for this reason the mesh writer might have decided not to set up this scheme. If so, we won't change this and suppress its creation...

p-adapt mesh, which exists in two representations, namely as:
- a FE mesh
- a forest of Oc or QuadTrees
p-refinement/derefinement process is documented (in tecplot-able form) if requested.
Procedure:
- Loop over all elements and do the p-refinement/unrefinement for those who want to be refined. Note: p-refinement builds fully- functional elements.
- For all nodes that were hanging on the previous mesh (and are still marked as such), fill in their nodal values (consistent with the current hanging node scheme) to make sure they are fully functional, should they have become non-hanging during the mesh-adaptation. Then mark the nodes as non-hanging.

- run a quick self-test on the neighbour finding scheme and check the integrity of the elements (if PARANOID)
- doc hanging node status, boundary conditions, neighbour scheme if requested.
After adaptation, all nodes (whether new or old) have up-to-date current and previous values.
