Combined Networks
This section lists the nets that contain mixed topologies, namely combinations of meshes and strands.
District
Display of a small district with different height information and with water as fluid.

- water_district_grid(method='nikuradse')
- Parameters:
method (str, default "nikuradse") – Which results should be loaded: nikuradse or prandtl-colebrook
- Returns:
net - STANET network converted to a pandapipes network
- Return type:
pandapipesNet
- Example:
>>> pandapipes.networks.simple_water_networks.water_district_grid(method="pc")
Mixed Network
Water network with a mesh in which one source appears.

- water_combined_mixed(method='colebrook')
- Parameters:
method (str, default "colebrook") – Which results should be loaded: prandtl-colebrook or swamee-jain
- Returns:
net - OpenModelica network converted to a pandapipes network
- Return type:
pandapipesNet
- Example:
>>> pandapipes.networks.simple_water_networks.water_combined_mixed(method="swamee-jain")
Versatility
Network with one pump, two sources and two opened valves.
Water:

- water_combined_versatility(results_from='openmodelica', method='colebrook')
- Parameters:
results_from (str, default "openmodelica") – Which converted net should be loaded: openmodelica or stanet
method (str, default "colebrook") – results_from = “stanet” -> nikuradse or prandtl-colebrook, results_from = “openmodelica” -> prandtl-colebrook or swamee-jain
- Returns:
net - STANET resp. OpenModelica network converted to a pandapipes network
- Return type:
pandapipesNet
- Example:
>>> pandapipes.networks.simple_water_networks.water_combined_versatility(method="")
Gas:

- gas_versatility()
- Returns:
net - STANET network converted to a pandapipes network (method = “prandtl-colebrook”)
- Return type:
pandapipesNet
- Example:
>>> pandapipes.networks.simple_gas_networks.gas_versatility()
Parallel
Gas network with the characteristic of three parallel pipes between two junctions.

- gas_3parallel(method='nikuradse')
- Parameters:
method (str, default "nikuradse") – Which results should be loaded: nikuradse or prandtl-colebrook
- Returns:
net - STANET network converted to a pandapipes network
- Return type:
pandapipesNet
- Example:
>>> pandapipes.networks.simple_gas_networks.gas_3parallel(method="n")
