From the equations we have
eps = eps_{m} + eps_{sw},
with eps_{sw} = -C_el^{-1} sigma_{sw}.

All other places are using correct sign.

solid_grain_pressure used in some density models was
not set and caused an access error in the ExponentialProperty.

Using central differences for Jacobian computation.
