How to relate an analytical mathematical expression to a geometry

Please login with a confirmed email address before reporting spam

Hello

Due to an assignment we try to simulate the diffusion of helium throught a geometry. The inlet and outlet of the geometry was determined, and the helium diffusion is given by an analytical mathematical expression.

The issue we want help in, is that how we can combine our mathematical flux expression to the geometry, so a diffusion throught it is can be simulated?

First we took "laminar flow" physics into account and thought that an analytical expression could be specifyied from this physics. Appearantly this physics only gives velocity and pressure simulations.
