The Inertial coordinates, the inverse Jacobian from the Grid to the Inertial frame, the Jacobian from the Grid to the Inertial frame, and the Inertial mesh velocity.
The type is a std::optional, which, when is not valid, signals that the mesh is not moving. Thus, coordinates_velocity_and_jacobian.has_value() can be used to check if the mesh is moving.
