Coupled heat and mass transport material model - HeMotk
=======================================================

Coupled heat and mass transfer material model.
Source: T. Krejci doctoral thesis; [Bazant:72]_;
Pedersen, 1990. Assumptions: water vapor is the only driving
mechanism; relative humidity is from range 0.2 - 0.98 (I and II
regions). The model parameters are summarized
in :numref:`hemotk_table`.
