Hoo Boy! Relaxing in Excel is fun! I never had an occasion to do it before....

Someone posted references to some templates, which I discarded

without a thought. Now I am filled with remorse, and would like to

see them posted again.

Here's my contribution: spreadsheets for solving Laplace's equation with

almost-any boundary conditions:

http://www.monmouth.com/~jsd/physics/laplace.html

which documents and points to

simple version:

http://www.monmouth.com/~jsd/physics/laplace.xls

advanced version:

http://www.monmouth.com/~jsd/physics/laplace-adv.xls

rotationally-invariant version:

http://www.monmouth.com/~jsd/physics/laplace-rot.xls

I have revised and enlarged the documentation. It now includes

-- a discussion of conservation of charge,

-- a discussion of gauge invariance

-- an improved discussion of over-relaxation

-- an improved discussion of the Laplacian in non-rectangular coordinates

I also cleaned up the spreadsheet formulas a bit.
