You want to add dof.clear() in the destructor of the object that owns
the triangulation that way you can clear the DoFHandler before the
Triangulation is destroyed. So you will have to change your
interface... Another thing you could try is something like this:
def run(inp,geo):
state = pystate.State1D(inp, geo);
equation = pyeqfactory.EqFactory1D.New(state)
eigenprob = pyeigenprobfactory.EigenProbFactory1D.New(state, equation)
solver = pyeigensolver.EigenSolver1D(state, eigenprob)
inp = pyinput.Input("heter1d/1d1g_heter")
geo = pygeom.ProbGeom1D(inp)
run(inp,geo)
when you exit run, all the object should (hopefully) be destroyed,
then you can safely destroy geo.
Best,
Bruno
