Two activities are on same day

[infoo_]

Hello

I want to know if there is a constraint to place A1 and A2 on same day, but not necessarily continuous (more flexible than ordered, grouped or consecutive).

Thank you!

Ordered is something else than you consider here.

Activities same starting day (any times).

Activities same starting day (any times).

Thank you! It is a constraint I never use

The output will be the same if I add a teacher and assign A1 and A2 to him, then teacher max days per week=1?

I think so.
