Continuous subject

[hipl]

Hi

I have a teacher X and he has special projects 10 periods/week and these 10 periods should be given to the teacher 5 periods continuous one day and the other 5 again continuous any other day.
The constraint is he should have 5 periods continuous on any two days. How do i achieve it?
I tried using " A set of activities has a set of preferred  starting time" in this i have defined the constraint as defined in image but it does not work, please help

Thank you...

2 Splits each with duration of 5 periods.

Yes i have given two splits of 5 periods each, but the time table generation stops at this constraint and does not proceed...

First remove the constraint "A set of activities has a set of preferred  starting time" and try again
