First:

Replace this line : bc := (D[1](u(x, t)))(0) = 0, (D[1](u(x, t)))(l) = 0, u(x, 0) = cos(2*Pi*x/l)

with bc:=D[1](u)(0,t)=0,D[1](u)(l,t)=0,u(x,0)=cos(2*Pi*x/l);

But there is problem in your boundary conditions which should be revised

Can you give example worksheet where you have error ?

In Classic worksheet ok it work
