TroughPhysicalProcessHeat

Parabolic trough for industrial process heat applications

PySAM.TroughPhysicalProcessHeat.default(config) → TroughPhysicalProcessHeat

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.TroughPhysicalProcessHeat.from_existing(data, optional config) → TroughPhysicalProcessHeat

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

PySAM.TroughPhysicalProcessHeat.new() → TroughPhysicalProcessHeat
PySAM.TroughPhysicalProcessHeat.wrap(ssc_data_t) → TroughPhysicalProcessHeat

Load data from a PySSC object.

Warning

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

TroughPhysicalProcessHeat is a wrapper for the SSC compute module cmod_trough_physical_process_heat.cpp

Functions

class PySAM.TroughPhysicalProcessHeat.TroughPhysicalProcessHeat

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
