TroughPhysicalIph

TroughPhysicalIph

PySAM.TroughPhysicalIph.default(config) → TroughPhysicalIph

Load defaults for the configuration config. Available configurations are:

• “PhysicalTroughIPHLCOHCalculator”

• “PhysicalTroughIPHNone”

Note

Some inputs do not have default values and may be assigned a value from the variable’s Required attribute. See variable attribute descriptions below.

PySAM.TroughPhysicalIph.from_existing(data, optional config) → TroughPhysicalIph

Share data with an existing PySAM class. If optional config is a valid configuration name, load the module’s defaults for that configuration.

PySAM.TroughPhysicalIph.new() → TroughPhysicalIph

PySAM.TroughPhysicalIph.wrap(ssc_data_t) → TroughPhysicalIph

Load data from a PySSC object.

Warning

Do not call PySSC.data_free on the ssc_data_t provided to wrap()

TroughPhysicalIph is a wrapper for the SSC compute module cmod_trough_physical_iph.cpp

Interdependent Variables

The variables listed below are interdependent with other variables. If you change the value of one of these variables, you may need to change values of other variables. The SAM user interface manages these interdependent variables, but in PySAM, it is up to you change the value of all interdependent variables so they are consistent. See Interdependent Variables for examples and details.
