Why not OO? This is a good problem for OO. For example: there is a
base class (BaseMesh) that will take care of loading your
mesh,provide a generic (possibly empty) refine() method, output the
mesh and have a bunch of utility functions. You can put that in a
module like meshing.py.
Then the user will do:
--------------------------------------------
from meshing import BaseMesh
class UsersMesh(BaseMesh):
def __init__(self,...):
BaseMesh.__init__(self,...)
....etc. initializer...
def refine(self,...):
...user's refine method would go here...
--------------------------------------------------
So for each different refine() method the user can derive a new class
from BaseMesh and overload the refine(...) method.
Hope that helps,
