Hallo all!

In Cfx 4.4 the porous flow model consider the Bruggemann correction for the diffusivities?

D_eff=D*por^1.5 (D=diffusivity, por=porosity)

Thanks in advance

In USERDIF, loop over the porous region and set your diffusivity manually to rho*D*por^1.5

Note you must set rho*D (or Gamma) in CFX-4.
