Who has any idea why NDSolve[{u''[t] + 1/2 u'[t] + Sin[u[t]] == 3/2 Sin[2/3 t], u[0] == 0, u'[0] == 0}, u, {t, 0, 200}, WorkingPrecision -> precision, MaxSteps -> Infinity] works if precision=50 but not if precision=60 ? (Error test failure at t=0.012758...) (tested with Mathematica 7.0) Thanks in advance A. Hautot (ahautot at ulg.ac.be)
