Quick fix: Replace equation with algorithm :)

Or use an initial equation instead of an when initial() clause ;)

I just opened ​OMCompiler#1604 to fix this.

Replying to janK:

I just realized that a when initial() clause will be evaluated twice if it is part of an algorithm section.

I saw it too, but didn't pay a lot of attention to it. Only with print this flaw was revealed - what a coincidence. Probably it is still worth fixing that. Issues could result if in initial() files (for writing e.g. results) are opened twice.

Right, seems not be a big issue yet. Anyway, I will fix it with ​OMCompiler#1607.
