The ebweyl module provides :

A FiniteDifferencing class with 4th (default) and 6th order backward, centered, and forward schemes. Periodic boundary conditions are used by default, otherwise a combination of the 3 schemes is available.
A Weyl class that computes for a given metric the variables of the 3+1 formalism, the spatial Christoffel symbols, spatial Ricci tensor, electric and magnetic parts of the Weyl tensor projected along the normal to the hypersurface and fluid flow, the Weyl scalars and invariant scalars.
Functions compute the determinant and inverse of a 3x3 or 4x4 matrice in every position of a data box.

  EBWeyl computes the electric and magnetic parts of the
  Weyl tensor, Eαβ and Bαβ, using a 3+1 slicing formulation.
  The module provides a Finite Differencing class with 4th
  (default) and 6th order backward, centered, and forward
  schemes. Periodic boundary conditions are used by default;
  otherwise, a combination of the 3 schemes is available. It
  also includes a Weyl class that computes for a given
  metric the variables of the 3+1 formalism, the spatial
  Christoffel symbols, spatial Ricci tensor, electric and
  magnetic parts of the Weyl tensor projected along the
  normal to the hypersurface and fluid flow, the Weyl
  scalars and invariant scalars. EBWeyl can also compute the
  determinant and inverse of a 3x3 or 4x4 matrice in every
  position of a data box.
