need help with the sheet, which has a fail odesolve

what can I do?

I just want to find the pathline and streakline from a velocity field,

BTW why the two velocity field plot at different time look exactly the same while is should really be different?

Type M1-M2 or N1-N2 show the two field is different., so what is happening?

Thanks

Odesolve fails because your equations "blow up" before the end time. If you set tend = 0.49 the odesolve works and you can see what is happening to y and z.
