[TRNSYS-users] Trnsed and parameters cycle

Thu Dec 8 10:01:39 PST 2011

Thibaut,
I can't think of a clean way of doing that. There are only two kinds of
groups in TRNSED that control whether or not another group is visible:
radio buttons and check boxes. My only suggestion (which is essentially
the same as what you came up with - except that it uses radio buttons)
is that you can have a radio button group that asks the user how many
walls they want to enter:

One wall
Two walls
Three walls
Four walls

You would then have to define one group for each radio button option
that contains all the inputs for N walls (where N is the number that the
user chose). Again, not very clean and basically the same result as your
check box idea.

Kind regards,
David
