this means (for me) an option: either to write out in *.msh all data 
OR creating a map (by gmsh2dolfyn: gmsh 3D elements <-> dolfyn 
cells, gmsh 2D named(!) elements <-> dolfyn boundaries). Using the 
map the default boundaries (region 0, when present) will not appear 
in the *.msh file. 

splitting the results will mean something like (the method of 
keeping the basename and extended extentions; great idea too for 
unsteady results!):

gmsh mymesh.msh mymesh_uvw.msh mymesh_p.msh mymesh_k.msh

(better this method than using View[i].Visible=0 which means one 
still creates the data set)

Instead of the background mesh; is it possible to ask Gmsh to refine 
certain specific cells? Sent to Gmsh for example by a list? 
The 'injection' of the 'current result' as the starting guess for 
the 'new mesh' would be simple then (only the refined 
elements/cells did change).
