Find the location in the global coordinate system for a local coordinate This function is the opposite of get_coords.

Get the inverse jacobian of the transformation. This one is needed to translate local gradients into global gradients. Hence it is crucial for calculating gradients of fields, or constructing finite elements.

Check whether mesh can be altered by adding nodes or elements.

Get the jacobian of the transformation. In case one wants the non inverted version of this matrix. This is currently here for completeness of the interface

Locate a node inside the mesh using the lookup table.
If there are no nodes we cannot find a closest point
Check first guess
This looks incorrect - but it is correct We need to do a full shell without any elements that are closer to make sure there no closer elements in neighboring searchgrid cells

These are here to convert indices to unsigned int counters. Some how the decision was made to use multi dimensional indices in some fields, these functions should deal with different pointer types. Use the virtual interface to avoid all this non sense.
