Analysis.exact_solution(mesh_name, field_name, time, zidx=None)[source]

Get the exact solution

Parameters

  • mesh_name (str) – The mesh name which is the prefix for the initial condition file

  • field_name (str) – The name of the variable of which we evaluate convergence For the default method, we use the same convergence rate for all fields

  • time (float) – The time at which to evaluate the exact solution in seconds. For the default method, we always use the initial state.

  • zidx (int, optional) – The z-index for the vertical level at which to evaluate the exact solution

Returns

solution (xarray.DataArray) – The exact solution with dimension nCells
