Also your call to sol[..] does not match the definition in the notebook you attached. (It seems to match the one from my previous file, but that one may not be what you want.) p = {1, 1.1}; While[p[[2]] < 1.2, z = zt[p[[2]], p[[1]], t0]; ss = Block[{tf = 0, xf = 0, yf = 0, dxf = 0}, Reap[While[tf < 10, Sow[sol[p, tf, xf, yf, dxf]]]][[2, 1]]; (*<-- *) p = {p[[2]], p[[2]] + z};]] Putting Reap outside Block will give a result, but maybe not what you want: ss = Reap[ Block[{tf = 0, xf = 0, yf = 0, dxf = 0}, While[tf < 10, Sow[sol[p[[1]], tf]]]; (*<-- or p[[2]]? Or? *) p = {p[[2]], p[[2]] + z};]][[2, 1]] It save only the result of the last iteration of the While loop in the variable ss. The previous results are discarded. Also keep in mind that While returns Null unless Return is used. To remove the vertical lines in the plot, try Plot[f, {t, 0, 10}, Exclusions -> (#[[1, 1, 2, 1, 1, 2]] & /@ ss)] where ss is list of solutions as in your notebook. URL: ,
