 \item The Viscosity Package can use temperatures from the GWE model to adjust the viscosities in the flow model.   
 
-\item GWE and GWT use the same Source and Sink Mixing (SSM) Package for representing the effects of GWF stress package inflows and outflows on simulated temperatures and concentrations.  In a GWE simulation, there are two ways in which users can assign concentrations to the individual features in these stress package.  The first way is to activate a temperature auxiliary variable in the corresponding GWF stress package.  In the SSM input file, the user provides the name of the auxiliary variable to be used for temperature.  The second way is to create a special SPC file, which contains user-assigned time-varying temperatures for stress package features.

 \item The GWE model includes an Energy Storage and Transfer (EST) Package that is analogous to the MST Package in the GWT Model.  The GWE Model does not simulate immobile domains and therefore does not include an analog of the IST Package in the GWT Model.
