Hi!
Yes, I tried
sol=NDSolve[{eqns, cond},f,{t,0,1200}][[1]]; Plot[Evaluate[f[t]/.sol],{t,0,1200}],
but that was a pain. Thanks to Bobby I managed to solve my speed problem:
Instead of
sol=NDSolve[{eqns, cond},f,{t,0,1200}][[1]]; Plot[Evaluate[f[t]/.sol],{t,0,1200}],
I selected the specific solutions I needed, and Set them to a variable that then I plot:
sol=NDSolve[{eqns, cond},f,{t,0,1200}][[1]]; a=sol[[1, Something, 2]] b=sol[[1, Something+1, 2]]
Plot[{a[t],b[t]}],{t,0,1200}],
and that was it. However I don't understand this. Was the problem the "size" and "amount" of interpolated functions?
