lagrangian.Field.compute

Field.compute(self: lagrangian.core.Field, t: lagrangian::DateTime, x: float, y: float, cell: lagrangian.core.CellProperties = <lagrangian.core.CellProperties object at 0x7fdbfd78c870>) → object

Interpolates the velocity to the wanted spatio temporal position.

Parameters

• t (datetime.datetime) – Date to evaluate

• x (float) – Longitude Longitude expressed as degree

• y (float) – Latitude expressed as degree

• cell (lagrangian.CellProperties) – Cell properties of the grid used for the interpolation

Returns

U and V components of the velocities evaluated or None if the velocity is undefined for the requested space-time position

Return type

tuple, optional
