  • $\begingroup$ Hi Ulrich, doesn't StreamPlot just plot the velocity field rather than the trajectory x(t) parametrically? Also, it's a bit hard to tell whether the field shown above has singularities, but I have included a graph showing that the denominator of V(x,t) is definitely zero at points. Ideally I'd like to solve the ODE while dealing with the singular points. $\endgroup$ Commented May 3, 2021 at 11:41
  • $\begingroup$ @j.foobles You might plot your "trajectories" together with the stream plot, fits quite well! $\endgroup$ Commented May 3, 2021 at 12:33
  • $\begingroup$ @j.foobles If I plot B[0,t,5,1,1/2] in the range -2<t<2 I see a function without zeros! $\endgroup$ Commented May 3, 2021 at 12:39
  • $\begingroup$ Hi @Ulrich Neumann, I am a bit confused - perhaps some of the code copied across incorrectly from Mathematica. Nevertheless I am convinced that the denominator function has some zeroes, so I've attached a .nb file here: 1drv.ms/u/s!Ak_7kWMZ0x15hJpuG74r3VEUFQIkTQ?e=dbay6L $\endgroup$ Commented May 3, 2021 at 12:53
  • $\begingroup$ @j.foobles You evaluate the same streamplot as in my answer? $\endgroup$ Commented May 3, 2021 at 12:57
