TcstroughPhysical
- PySAM.TcstroughPhysical.default(config) TcstroughPhysical
Load defaults for the configuration
config. Available configurations are:None
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.TcstroughPhysical.from_existing(data, optional config) TcstroughPhysical
Share data with an existing PySAM class. If
optional configis a valid configuration name, load the module’s defaults for that configuration.
- PySAM.TcstroughPhysical.new() TcstroughPhysical
- PySAM.TcstroughPhysical.wrap(ssc_data_t) TcstroughPhysical

Warning
Do not call PySSC.data_free on the ssc_data_t provided to
wrap()
TcstroughPhysical is a wrapper for the SSC compute module cmod_tcstrough_physical.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.
