 Hello,I'm getting the following error when trying to numerically solve a PDE: NDSolve::fembdnl: The dependent variable in (P^(1,0))[0,t]==0 in the boundary condition DirichletCondition[(P^(1,0))[0,t]==0,x==0.] needs to be linear. Does anyone know what this means or how to avoid the error?The code is provided below as an image and attachment.Thank you,Abed Attachments:
