Hi, I'm trying to numerically solve this 5th order, non linear ODE:
Li[t]i'[t]+R(i[t]^2)+b(i''[t]^2)
-di'[t]i''[t]-fi''[t] i'''[t]
-g i'''[t] i''''[t]- h i''''[t]i'''''[t]=0

for boundary conditions i[0]=A, i'[0]=0,
i''[0]=0,i'''[0]=0,i''''[0]=0

The error I get is: Power::infy: Infinite expression 1/0 encountered

There were several similar posts on this, but their recommendations are not helping.

The nb file is attached with several attempts from the similar posts.... Thank you for any insight or help. I've been looking at this for a while...

-John
