two teachers, each one has one activity per week in the same 10 classes
Any couple of this activities (one for each teacher in the same class) must happen in the same day of week,
(to be swapped in some weeks of the year) all others can be totally independent.
depending an your dataset there are several solutions.
in easiest case you just place to teachers into the same activity.
or you use same starting time constarint to both activities.
or you do a forthnightly trick. see: http://www.timetabling.de/manual/FET-manual.en.html#id_36
thanks Volker,
but with all of your solutions I must choose the couple of activities and impose constraint on that couple.
But for me is totally indifferent which couple of activities happen in the same day: so I would leave to FET the decision about which one to use for the day sharing.
i fear i don't understand your request.
please explain one more detailed.
please also explain your idea. maybe i missunderstood. you mean you just want to do that because of swapping after some weeks?
in that case: yes. select it. i also do that if i setup our half year timetable. (teacher have only 1 hour per year. i just give them 2 hours for 0,5 years. in sum that is the same. So i swap the timetable after 0,5 years. i just select it. that is activity planning in fact; not timetabling. the "only" wrong thing you might do there is if you don't spread special room activities evenly or of teacher need special free days (for example the rookie teachers)

I am sorry, but I cannot see a solution.
thanks to Liviu and Volker
i will choose which couple of activities share the day and impose constraint on that one.
