[CIG-MC] CIG-MC Digest, Vol 99, Issue 3

[Thorsten Becker]

look into the ggrd options of CitcomS in terms of reading in Netcdf/GMT grd
files given in map view for several layers. those allow you to assign
arbitrarily complex geometries to temperature, composition, and viscosity
material, e.g. 3D seismicity based slab structures, as used, for
example in Alpert
et al. (2010) <http://geodynamics.usc.edu/~becker/preprints/abb10.pdf>
