atl_modg_scaledTransposedInvMassMatrix_Q Subroutine

public subroutine atl_modg_scaledTransposedInvMassMatrix_Q(nTotalElems, nDofs, nScalars, maxPolyDegree, nElems, state)

Applies a scaled transposed inverse of the mass matrix for a 3D scheme. The result is a transformation of the polynomial basis from the ansatz- to the test-polynomials. This is useful for a local predictor
