Query: Higher-Order Multilevel Framework for ADER Scheme in Computational
  Aeroacoustics   The versatile Arbitrary-DERivative (ADER) scheme is cast in a multilevel
framework (ML-ADER) for fast solution of system of linear hyperbolic partial
differential equations. The solution is cycled through spatial operators of
varying accuracy while retaining highest-order accuracy by the use of a forcing
function. Accuracy analysis of the multilevel framework including in the
ML-ADER form is carried out in time-domain as well as frequency-domain. Results
are obtained for benchmark problems in computational aeroacoustics at a much
reduced computational cost.
