Spreadsheet
Finite Differences Method

Foxes Team

 

 

Step by step, how to solve PDE, boundary value problems
using common spreadsheets like Excel, Calc or Lotus 123

 

Greetings. This material comes from the collaboration, in the summer of 2004, between our team and Chatchawan Vongmahadlek, Thai engineer, that had developed a set of smart iterative methods to apply Excel to the solution of PDE and ODE with boundary and initial conditions. The application was so brilliant that we have dedicated many of our time to this very interesting topic. We have organized and integrated the material kindly gives us by Chatchawan and we have developed a set of VBA macros for solving FD problems, hoping all this effort will delight same other people
