example after one step (I can't attach two files)
I wish to solve the two dimensional Laplace equation by the relaxation method.
To do this, I chose a region of the spread sheet enclosed in cells holding
constant numerical values. Interior cells hold formulas like, for B2:
=(B1+B3+A2+C2)/4.
See Laplace0.ods; This amounts to a large number of circular references. I
check iteration, chose step number 1, error bound 0.1, uncheck automatic
calculation and press F9; I get Laplace1.ods, error 523 in every variable cell.
Changing step number or error bound makes no difference. In contrast, the
one-dimensional case (as in the help for circular reference) works well. What
do I do wrong ?
Related question: once the computation stops, with error 523, how can I restart
it without retyping the speadsheet?
Remark: Over the years, I have run this type of computation successfully on
Quattro pro (!), Excel and OpenOffice.calc
