Data Structure

WAVI.jl uses a hierachical data structure, which is shown schematically below. This page provides a brief overview of each of these structures; you can find out more information about each of these via the tabs in the sidebar.

At the top of the hierarchy are Simulations. Simulations are to be ran! A Simulation object must be passed the sub-structures describing the following (terms in brackets are the names of the corresponding structures in WAVI.jl):

• Model (Model): contains all the information about the current state, parameters, initial conditions, and process parametrizations (see below).
• Timestepping Parameters (TimesteppingParams): contains parameters relating to timestepping (e.g. timestep, number of timesteps etc)
• Output Parameters (OutputParams): optional structure that contains information relativng to the outputting of solutions (what to output, when to output etc).

A Model structure contains sub-structures describing the following:

• Grid (Grid): contains information on the discretization of the model domain (e.g. number of grid cells, grid spacing etc)
• Physical parameters (Params): contains physical parameters (e.g. density of the ice)
• Solver parameters (SolverParams): contains parameters relating to the velocity solver (e.g. maximum number of iterations)
• Initial conditions (InitialConditions): stores initial conditions relating to the ice sheet.
• Fields (Fields): stores information on the current state of the model.
• A basal melt rate model (MeltRate): contains information on how basal melting is parametrized in the model.
