Thanks Robert for your suggestion.
>Why not simply use a gradient across the specimen and get the flow.getBoundaryFlux() function?

I don't know the meaning of ‘gradient’ very well.If I set the flow condition as follows, the value of flow.getboundaryflux() I get seems to remain unchanged..
###
flow.permeabilityFactor=1
flow.boundaryUseMaxMin=[0,0,0,0,0,0]
flow.bndCondIsPressure=[1,1,1,1,1,1]
flow.bndCondValue=[0,0,0,0,0,Sy]
###
(About cylinder,is boundaryUseMaxMin=[0,0,0,0,0,0] suitable?)

>You should be putting your custom permeability() function into a
PyRunner().

This is a good idea. I can reduce the calculation time by increasing
iterperiod, but if I use this method, how should I record the calculated
permeabilities?(such as how to add it into plot.addData()?)

Cheers,
