Getting Started / System overview

The four major components of this system are:

  1. Configuration. There are many configuration settings, although at least initially, many of them can be ignored, as you learn the system.
  2. GRIB input. You provide GRIB data which describes wind forecasts, ocean current and wave height data. Only the wind data is required. (In addition, multiple wind forecast files can be provided - although this is left as a future, more advanced topic, discussed in the manual.)
  3. Running the solver.
  4. Analysing the output. There are many ways to examine what the solver has generated.

Switching modes.

To start working with the weather routing system, you need to choose the weather routing tool, by clicking on the icon on the right of the tools group:

When you do that, the sidebar on the left will display new content. Normally the sidebar is split into two, with the top being the list of files available and the bottom being the list of draw presets that are used to visualize the GRIB files in different ways.

When you invoke the weather routing tool, the bottom area of the sidebar becomes something like this:

The tool is described in more detail in its own section.


Another major component of this system is how the weather routing solver interacts with vessels. You will notice in the above image that there are two settings areas:

These are both described in more detail soon. However, briefly, the first setting are all of the settings which apply to a vessel. In this case, there is a vessel named “Neah-Hawaii.” The system is capable of supporting as many vessels as you want to create. Each vessel can have different performance characteristics, be located in a different part of the world, and each has independent settings which describe to the solver what it wants to accomplish.

Everything else.

There is quite a lot more to describe. Please read through the other topics in this Getting Started guide for more detail.
