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?
