You may find solutions of boundary value problems of partial diff. equ. without using finite elements or similar methods, but using collocation methods together with Mathematica and downloadbale codes in Mathematical Methods in Physics and Engineering using Mahtematica, CRC PRess, 2003, ISBN 1-58488-402-9.COdes may be donwloaded from www.crcpress.com, containing closes and-or analytical expressions.
