[CIG-SHORT] Distance along fault

[Brad Aagaard]

Christian,

The easiest way to access nodal coordinates in an Exodus file is via 
Python. The PyLith binary includes the netCDF Python module for 
accessing netcdf files (Exodus is a specialized netcdf file). See 
examples/meshing/cubit_cellsize/exodus_add_properties.py for an example 
of how to access the Exodus file via Python. Also see the last few lines 
of examples/2d/subduction/afterslip_tractions.py for how to write a 
spatial database file via Python.

Regards,
Brad

I'm able to export the whole mesh in exodus format then using ncdump to get an ascii file but it only works for the whole mesh. Would it be possible to export only nodes from a nodeset?

The main reason for not supporting local coordinate systems is they depend on the geometry and discretization of the finite-element model. One of the main features of the spatial databases is that they are independent of the discretization and geometry of the model. That is, you can change the finite-element model and the same spatial database will give the same spatial variation in values.
