Nonholonomic Newmark method (2201.13162v1)
Published 31 Jan 2022 in math.NA, cs.NA, math-ph, math.DG, and math.MP
Abstract: Using the nonholonomic exponential map, we generalize the well-known family of Newmark methods for nonholonomic systems. We give numerical examples including a test problem where the structure of reversible integrability responsible for good energy behaviour as described in [16] is lost. We observe that the composition of two Newmark methods is able to produce good energy behaviour on this test problem.
