rhaven is still having a problem:
Hi Bruno,
Thank you for the quick reply. Ive added flow.emulateAction() as well as the following boundary conditions (otherwise i would get a bus error) 
	flow.dead=0
	flow.defTolerance=0.3
	flow.meshUpdateInterval=200
	flow.useSolver=3
	flow.permeabilityFactor=1
	flow.viscosity=10
	flow.bndCondIsPressure=[0,0,1,1,0,0]
	flow.bndCondValue=[0,0,1,0,0,0]
	flow.boundaryUseMaxMin=[0,0,0,0,0,0]
	O.dt=0.1e-3
	O.dynDt=False
	flow.emulateAction()
	flow.saveVtk()

The console output however from saveVtk() is:

Segmentation fault (core dumped)

What does Vh=NULL mean and is this the cause of the CHOLMOD and
segmentation fault?

thank you
