4484	Model becomes singular if equations are written inside if-else	pravinkumar.dalve@…	Lennart Ochel	"Please see the attached file.

In Column1 model if I write reboiler.feed.-- equations for some variables inside if-else, the model becomes singular. If I write these equations in algorithm outside if-else statement, model works fine.

I am having eight variables in same if-else statement but only four of them behaves like this. 

Thank you in advance.
