I was wondering whether it could be possible in one of next releases to assign a mesh background field through a list of points with associated control length, i.e.:
[x, y, z, lc]_i , i=1,...,N
This would be quite handy for an automatic grid refinement procedure...

The issue is that we need to be able to interpolate the values. Without a mesh you could use e.g. radial basis functions. Feel free to submit a merge request with such a field: it could indeed be interesting!
