Snowmodel¶
Wrapper for SAM Simulation Core model: cmod_snowmodel.cpp
Creating an Instance¶
There are three methods to create a new instance of a PySAM module. Using default populates the newclass’ attributes with default values specific to a config. Each technology-financialconfiguration corresponds to a SAM GUI configuration. Using new creates an instance with empty attributes. The wrap function allows compatibility with PySSC, for details, refer to PySSC.
Snowmodel model description
Snowmodel
-
PySAM.Snowmodel.default(config) → Snowmodel¶ Use financial config-specific default attributes
-
PySAM.Snowmodel.from_existing(data, optional config) → Snowmodel¶ Share underlying data with an existing PySAM class. If config provided, default attributes are loaded otherwise.
-
PySAM.Snowmodel.new() → Snowmodel¶
-
PySAM.Snowmodel.wrap(ssc_data_t) → Snowmodel¶ Use existing PySSC data
Warning
Do not call PySSC.data_free on the ssc_data_t provided to
wrap
Functions¶
-
class
PySAM.Snowmodel.Snowmodel¶ This class contains all the variable information for running a simulation. Variables are grouped together in the subclasses as properties. If property assignments are the wrong type, an error is thrown.
-
assign(dict) → None¶ Assign attributes from nested dictionary, except for Outputs
nested_dict = { 'PV Snow Model': { var: val, ...}, ...}
-
execute(int verbosity) → None¶ Execute simulation with verbosity level 0 (default) or 1
-
export() → dict¶ Export attributes into nested dictionary
-
value(name, optional value) → Union[None, float, dict, sequence, str]¶ Get or set by name a value in any of the variable groups.
-
PVSnowModel Group¶
-
class
PySAM.Snowmodel.Snowmodel.PVSnowModel¶ -
assign() → None¶ Assign attributes from dictionary
PVSnowModel_vals = { var: val, ...}
