Variables

We provide the following methods to provide a compositional approach for defining common variables used in gas flow models. These methods should always be defined over "AbstractGasModel".

GasModels.variable_compressor_ne — Function

variables associated with building compressors

source

GasModels.variable_compressor_ratio_sqr — Function

Variable Set: variables associated with compression ratios

source

GasModels.variable_connection_direction — Function

variables associated with direction of flow on the connections. yp = 1 imples flow goes from fjunction to tjunction. yn = 1 imples flow goes from tjunction to fjunction

source

GasModels.variable_connection_direction_ne — Function

variables associated with direction of flow on the connections yp = 1 imples flow goes from fjunction to tjunction. yn = 1 imples flow goes from tjunction to fjunction

source

GasModels.variable_flow — Function

Variable Set: Define variables needed for modeling flow across connections

source

GasModels.variable_flow_directed — Function

Variable Set: Define variables needed for modeling flow across connections where some flows are directionally constrained

source

GasModels.variable_flow_ne — Function

Variable Set: Define variables needed for modeling flow across connections that are expansions

source

GasModels.variable_flow_ne_directed — Function

Variable Set: Define variables needed for modeling flow across connections that are expansions and some flows are directionally constrained
