Two Consecutive lectures issue of a subject in a day

[TAHIR]

A subject have 7 lectures per week ( 5 days/week timetable) , how is it possible that 2 lectures must not be consecutive on any day?
Which constraint is use so that two consecutive lectures of same subject not be placed in a day?

[Liviu Lalescu]

Add (1+1+1+1+1) and (1+1), then min 1 gaps between activities. Or use min gaps between activity tags for students/teachers.

[TAHIR]

Min 1 gaps between activities just for activities (1+1).
Or
Add For both activities (1+1+1+1+1) & (1+1) ?

[Liviu Lalescu]

For all 7 of them.

Before doing that work, I recommend to talk with the teacher of that activity. Most teachers like to have the hours consecutive, since from a pedagogic view it is in many cases better to have no break in between.

Some teachers demanding consecutive two periods but some demands separately. So
