## Public Types

using type = std::optional< std::tuple< tnsr::I< DataVector, Dim, Frame::Inertial >, ::InverseJacobian< DataVector, Dim, Frame::Grid, Frame::Inertial >, ::Jacobian< DataVector, Dim, Frame::Grid, Frame::Inertial >, tnsr::I< DataVector, Dim, Frame::Inertial > > >

## Detailed Description

template<size_t Dim>
struct domain::Tags::CoordinatesMeshVelocityAndJacobians< Dim >

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.
