I am trying to use the StateData feature for solving a PDE, such as the Kuramoto-Sivashinksy equation. However, I keep getting this strange error that I cannot figure out.
Attached is a screenshot of my input and the error. I have been able to solve this KS equation using NDSolve, but I cannot seem to get the StateData feature to work for it. It seems to be evaluating the initial conditions (both the spatial and the temporal one) to either true or false, but they shouldn't be evaluated like that!
Thanks in advance for any help you may be able to provide.
