Dear all,

Some years ago, I worked out a beam calculation tool in smath, based on singularity functions.
The sheet worked flawless in an older SMath version, but the most recent SMath-incarnations result in problems: the error seems to originate with the summation command.
How do I get this program working again?

I attach the original files: thanks for any feedback!

Kind regards from a Belgian SMath-fan,

Jan

Hello.

This is because of using "i" as a variable. Currently we have some issues regarding it. Will be addressed soon.

Simple change to fix your worksheet:

Alternately: define the summations as local variable [SS 6179]
The document concludes the project.
