Compute traveling wave solution to PDE as a time-independent problem

I encounter a problem in which I need to to find the traveling wave solution to a PDE, for example
du/dt = d^2(u)/dx^2 + u*(1-u)
After substituting the traveling wave ansatz u(x,t) = w(s=x-vt) into the above equation, it becomes an ODE with an unknown velocity v:
-v*dw/ds = d^2(w)/ds^2 + w*(1-w)
I'm wondering if there's a way to solve such an equation in COMSOL as a time-independent problem. Your thoughts are appreciated. Thanks in advance.

Ming
