Biot's Modulus and coefficient in el2p model
Hi Edscott,
yes, the model assumes alpha = 1. If you want to adapt this, you have to change
it in the elementvolumevariables.hh, but also for the assembly of the momentum
balance equation in localoperator.hh:346 (- alpha * peff instead of - peff

Hi Edscott,
just as an addition: modifying the porosity-model (storage term) is a
lot easier in Dumux 3.0.
You simply have to change the porosity law in the spatialparams.

The post-processing evaluation of the total
We are now introducing Biot's modulus into the el2p problem and using this to
calculate Skempton's coefficient instead of the other way around (Biot's
modulus = 1/c0_).
In order to obtain the undrained bulk modulus we also need Biot's coefficient
(alpha), so we also provide that in the input
