While GMS supports most of the UTCHEM options, some options are not currently available in the current UTCHEM phase of GMS. All of these options can be added manually to the file created by GMS. The options not supported by the GMS inteface to UTCHEM include:
Certain time step options
Automatic time step size selector based on method of relative changes for all components.
Automatic time step size selector based on changes in dimensionless concentration for all components
Concentration well model
Capacitance model
Gel reactions
Biodegradation reactions
Certain coordinate systems
Radial
Cartesian variable-width gridblock
Curvilinear grid
Tracer reactions
Temperature variation
Polymer species
