Group lessons arranged in order in 1 session (day) in the morning and afternoon

Hello Liviu. I have a small problem I want to ask for help on FET
Case 1: Teacher A teaches 2 subjects in class 6A: Chemistry and Biology. Chemistry: 2 consecutive periods, students 2 consecutive periods
Case 2: Teacher A teaches 4 subjects in class 6A, which is chemistry, 6B is physics, 6C is biology, and 6D is history. Chemistry (1 hour), physics (1 hour), Sinh (1 hour) and history (1 hour).
How do I create a tie in case 1: chemistry and biology are lined up in any one session, morning or afternoon
Case 2: Those 4 subjects are placed together in the same morning or 1 afternoon.
Know the subjects can be reversed order: Chemistry-Biology; Biology-Chemistry; Chemistry-Biology-History; Biology-Chemistry-Physics-History

Hello, ngo,

I am so sorry, but I do not understand. If I understood something, you might want to use constraints min/max (real) days between activities and/or students/teachers activity tag max hours per real day (enable this constraint without worrying), adding a tag to the activities of a teacher in a students set.

Case 1: Teacher A teaches 2 subjects in class 6A: Chemistry and Biology. Chemistry: (2) and Biology (2)
Case 2: Teacher A teaches 4 subjects in class 6A which is chemistry, 6B is physics, 6C is biology and 6D is history. Chemistry (1), physics (1), Biology (1) and history (1 hour).
How do I bind in case 1 for 2 subjects chemistry and biology lined up in 1 morning or in 1 afternoon
Case 2 teaches all 4 subjects in 1 session (FET day)
Can you make me an attachment

[Liviu Lalescu]

Before I make you an example, I would like you to try for yourself. If you want 2 activities or 4 activities on the same FET day, there is the constraint activities same starting day. It should be easy.

I tried to make you a file. See the attached. Neglect the warning that it is created with FET-6.5.7, the next version, which is on my hard disk.

I made it according to the attached file
thank you Liviu. Have a good day
