  2. fourier

    i have 1-D heat PDE, and am required to solve it using Finite fourier cosine transform (FFCT), and one of the B.C equals U_1 , and someone said that you need to use stationary solution..
  3. stationary solution for u(x,t)=v(x,t)+h(x) for heat PDE with BC of U1

    what is the meaning of stationary solution h(x) and how can I find it for this equation u(x,t) =v(x,t) +h(x) for heat PDE with BC of U1, can you explain in details?
