Question about the custom FET for course planning

[bin_wang]

Dear Mr.Liviu&Volker, Thanks for your work, giving us an amazing time table software.
I'm using it to arrange our time table, but I have a question about the custom version.

In this version I can arrange my students into different classroom and it runs ok now.

But if one subject has  two teachers, for example(like the example fet file in the custom version) , subject Political  has two teachers T1 and T2, every teacher has 4 activities one week(etc. T1_1, T1_2, T1_3, T1_4 and T2_1, T2_2, T2_3, T2_4).

and if I have 2 students (s0, s1) who choose Political, now the custom version will arrange activities like this
(s0: T1_1 , T2_2, T1_3, T2_4)  (s1: T2_1, T1_2, T2_3, T1 ,4 )

But I want it to be like this (s0: T1_1, T1_2， T1_3, T1_4) , (s1: T2_1, T2_2 , T2_3, T2_4) or (s1: T1_1, T1_2， T1_3, T1_4) , (s0: T2_1, T2_2 , T2_3, T2_4) .  My students don't want to change his teacher in each activities of same subject , and for my teachers it's hard for them to know every students' progress if they keep changing classroom.

of course I can add one teacher to student when I setup activities, but I have 500 students will be split into 10 different optional course at same time , and every course has 2 or 3 teachers. so I just want to know if there are some tricky to handle this. for example when the first activity is set , the student know his teacher for the subject , and the subsequent activities will be set to the same teacher.

Would you pls tell me how can I set up the constraint to make sure  the student will not change the teacher in every subject but still they can be arranged into different classroom?

I'm not sure if I have express me clearly.
Thank you very much.

I did not examine very thoroughly your question, I am sorry for this, but this custom version is a bit difficult to use, even for me. And your question needs more time to read thoroughly.

If you are scheduling real students (= FET students) to real teachers (= FET rooms), I think you can use the constraint activities occupy max 1 different rooms to schedule real students to the same real teacher.

Thank you Mr. Liviu, it worked.
It seems to be a good solution. At least now the test result is ok for me.
Thanks!
