DTOcean Mooring and Foundations Example

Note, this example assumes the DTOcean database and the Electrical Sub-Systems Module has been installed

from IPython.display import display, HTML

import matplotlib.pyplot as plt
plt.rcParams['figure.figsize'] = (14.0, 8.0)

Create the core, menus and pipeline tree

The core object carrys all the system information and is operated on by the other classes



In [ ]:

    
new_core = Core()
project_menu = ProjectMenu()
module_menu = ModuleMenu()
pipe_tree = Tree()

Create a new project



In [ ]:

    
project_title = "DTOcean"  
new_project = project_menu.new_project(new_core, project_title)

Set the device type



In [ ]:

    
options_branch = pipe_tree.get_branch(new_core, new_project, "System Type Selection")
variable_id = "device.system_type" 
my_var = options_branch.get_input_variable(new_core, new_project, variable_id)
my_var.set_raw_interface(new_core, "Tidal Floating")
my_var.read(new_core, new_project)

Initiate the pipeline

This step will be important when the database is incorporated into the system as it will effect the operation of the pipeline.



In [ ]:

    
project_menu.initiate_pipeline(new_core, new_project)

Discover available modules



In [ ]:

    
names = module_menu.get_available(new_core, new_project)
message = html_list(names)
HTML(message)

Activate a module

Note that the order of activation is important and that we can't deactivate yet!



In [ ]:

    
module_name = 'Mooring and Foundations'
module_menu.activate(new_core, new_project, module_name)

Check the status of the module inputs



In [ ]:

    
mooring_branch = pipe_tree.get_branch(new_core, new_project, 'Mooring and Foundations')
input_status = mooring_branch.get_input_status(new_core, new_project)
message = html_dict(input_status)
HTML(message)

Initiate the dataflow

This indicates that the filtering and module / theme selections are complete



In [ ]:

    
project_menu.initiate_dataflow(new_core, new_project)

Load test data

Prepare the test data for loading. The test_data directory of the source code should be copied to the directory that the notebook is running. When the python file is run a pickle file is generated containing a dictionary of inputs.



In [ ]:

    
%run test_data/inputs_wp4.py



In [ ]:

    
mooring_branch.read_test_data(new_core,
                              new_project,
                              "test_data/inputs_wp4.pkl")

Check if the module can be executed



In [ ]:

    
can_execute = module_menu.is_executable(new_core, new_project, module_name)
display(can_execute)



In [ ]:

    
input_status = mooring_branch.get_input_status(new_core, new_project)
message = html_dict(input_status)
HTML(message)

Execute the current module

The "current" module refers to the next module to be executed in the chain (pipeline) of modules. This command will only execute that module and another will be used for executing all of the modules at once.

Note, any data supplied by the module will be automatically copied into the active data state.



In [ ]:

    
module_menu.execute_current(new_core, new_project)

Examine the results

Currently, there is no robustness built into the core, so the assumption is that the module executed successfully. This will have to be improved towards deployment of the final software.

Let's check the number of devices and annual output of the farm, using just information in the data object.



In [ ]:

    
output_status = mooring_branch.get_output_status(new_core, new_project)
message = html_dict(output_status)
HTML(message)



In [ ]:

    
economics = mooring_branch.get_output_variable(new_core, new_project, "project.moorings_foundations_economics_data")
economics.get_value(new_core, new_project)



In [ ]:

    
moorings = mooring_branch.get_output_variable(new_core, new_project, "project.moorings_component_data")
moorings.get_value(new_core, new_project)



In [ ]:

    
lines = mooring_branch.get_output_variable(new_core, new_project, "project.moorings_line_data")
lines.get_value(new_core, new_project)



In [ ]:

    
umbilicals = mooring_branch.get_output_variable(new_core, new_project, "project.umbilical_cable_data")
umbilicals.get_value(new_core, new_project)



In [ ]:

    
dimensions = mooring_branch.get_output_variable(new_core, new_project, "project.moorings_dimensions")
dimensions.get_value(new_core, new_project)



In [ ]:

    
network = mooring_branch.get_output_variable(new_core, new_project, "project.moorings_foundations_network")
net_val = network.get_value(new_core, new_project)



In [ ]:

    
import pprint
pprint.pprint(net_val)
