I am tyring to solve a mixed 4th order partial differential equation. It is of the form (with various constants in front of the terms):
(D[u[t,x],{t,2}] + D[u[t,x],{t,3}] + D[u[t,x],{t,4}]) - (D[u[t,x],{x,2}] + D[u[t,x],{x,2},{t,1}] + D[u[t,x],{x,2},{t,2}) == 0
My initial conditions/boundary conditions are:
u[0,x] == Exp[-x^2]
u[t,xmax] == 0
u[t,xmin] ==0
I’m having issues with how to specify the initial boundary conditions (how many do I need, and how to express them).
Any helpful hints/suggestions would be great!
Thanks,
Smitha
