[Camino-users] what is the permeability definition

[Hall, Matt]

Hi Stephania,

It's the probability that a particle will step through a barrier rather than be reflected by it. It is not normalised by time, it's defined per event. All units in camino are SI, so simulation time is measured in seconds. The relevant timescale for reflection events is the duration of a simulation update, which is the duration of the simulation (this is reported to the commandline if you're using a schemefile, or specified directly if using a trajfile) divided by tmax - the number of updates.

Hope this helps,
Matt.

Hi all Camino users
I am constructing different substrates with parallel cylinders and a fixed Gamma Distribution of radii. I would like to vary axonal wall permeability but I don't find its definition.
Is it the  fraction of incident particles succeeding in crossing the wall in the simulation unit time or not? If yes what is the simulation unit time?

Thanks a lot
Stefania Oliviero
