Explicit time stepping requires linear time-independent constraints

hello;

I am using 1-D PDE-wave equation node for simulating a simple wave propagation model. I have a rod which is fixed at one end and at the other end I apply a sinusoid displacement only with one period. I use time explicit solver to solve it by explicit solver but I get this error” Explicit time stepping requires linear time-independent constraints.” Why?

How could I apply explicit solver to work properly in this case?
cheers
