I have a problem with defining boundaru conditions id NDSolve of PDE F is function of [x,t] Conditions has form : (d/dx)F[0,t]==0; I wrote this in form : D[F[0,t],x]==0 Its TRUE (0==0) Then i wrote D[F[x,t],x] out: F(1,0)[x,t] ; {(1,0) looks like "power"} And "copy"&"paste", and changed x to 0 in arguments This way works, but I'm sure is a better way ?
