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?
