Most of the weather routing configuration is done in two areas: the configuration area in the sidebar and through the tool menu. This page describes the configuration area:
The system creates weather routing solutions for vessels, and multiple vessels can be created in the system. The menu associated with the Routing for: setting allows you to choose which vessel you are working with.
You can change the vessel at any time. Any previously created weather routing solutions for a vessel remain present when you switch vessels. This allows you to solve for one vessel, switch to a new vessel and solve again. After solving for two, or more, vessels the generated paths can be compared to each other.
If a vessel has had its visibility toggled off, it will not appear in this menu.
The second line changes its name according to the vessel that has been selected. Clicking on the reveal button to the right of this label opens the vessel settings editor. This is the editor which allows you to edit all of the settings associated with a vessel.
Example vessel settings are: starting point, vessel performance, tack/jibe penalty and many more.
There are a small number of system settings. These settings apply to all vessels that weather routing solutions are generated for.
One example system setting is the land clearance distance.
This editor allows you to type in the exact starting point for the weather routing solution, if you know what it is. You can also create the start point using the tool menu and dragging the point around the screen, or by creating a position report.
The current starting time is shown. To change the starting time, use the tool menu.
These are the GRIB files which will be used when the solver is next run. Note that the files reported in this area are not necessarily the files associated with a selected solution path.
There are three buttons in this area. If one of the three GRIB file types has an associated value, the button label will show the filename. Clicking on the button will select the file (allowing you to view the wind, wave or current file.)
If multiple wind files are being used by the solver, the wind button will show Multiple and clicking on it will bring up a menu with the files to choose from.
Clicking on the Solve button runs the weather routing solver. If this button is enabled, the system has enough input for the solver to run. If this button is not enabled, there should be a message displayed with a hint as to what is missing.
Clicking on the Clear all button will halt the solver if it is currently running, remove all pending solutions from the solvers queue, and remove all weather routing solutions.
The reveal button to the right of the Clear all button will bring up a logfile. The logfile may contain helpful messages, from time to time. If the solver has done something surprising to you, it may be worthwhile looking in this area.
Examples of messages you may find here are:
The message shown below the Solve button will change from time to time, according to what the system deems important.
The menu to the right of the Image label allows you to choose one of the analysis image types. See the Evaluating results section for more details.
The check buttons to the right of the Draw label turn on and off various elements that can be drawn.
These two buttons bring up corresponding windows that allows you to view and interact with either the entire collection of solutions present in the system, or to view details on the selected solution.
