The use of STELLA arrays in the SME is limited to map-dependent parameters, i.e. parameters, such as porosity, which depend on a spatially-varying index, such as soil_type. Thus the array must be a parameter ( i.e. take on a constant value for each value of the index ), and the array index must be an class (integer-valued) map ( i.e. configured with "c" config-cmd ).
The SME extracts the array data from the Stella model and writes it to a DBaseParameters.out file, which is read by the Driver at run-time and used to set up the map-dependent parameters. Any commands in the SME configuration files associated with Variables listed in the DBaseParameters.out file will override the information in that file. Thus, if a Varaible is declared as an array in STELLA but is declared as a parameter ( "pm" config-cmd ) in the SME config data, the Variable will be set up as a parameter in the Driver.
