Hi, Does anyone know how to solve the inverse problem of the diffusion equation by the finite element method or/and by FlexPDE5 ? Best regards.

FlexPDE was used several years ago at Lawrence Livermore Lab to solve a forward-inverse problem. The report on this work can be seen at http://www-afim.llnl.gov/ Appendix B of this report deals with the specific inverse solution method. A copy of this appendix is posted at www.pdesolutions.com/download/gelinas.appb.doc A lower-level report on the core problem grad(K)<dot>grad(H)=0 was written here at PDE Solutions Inc in 1997. This report can be downloaded from www.pdesolutions.com/download/hyperbolic.doc This report used FlexPDE version 2 and has not been updated since, but I presume the script translation should be straightforward. |
