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

Thanks for the answer, Matt.
I see what you explain, but I don't see if it can apply to my problem. For instance, if I continue with the type 16 example. My question is : If the end-user wants to implement a variable number of surfaces, how to implement that in a "user friendly" way.
The way I see now is to use a default type 16 with a given numer of surfaces, let's say ten. But if I don't want to see all inputs in the GUI, I need to use check boxes that make appear inputs for the "checked" surface. Is there a way to make it work the same way cycles work in Trnsys, with a numer defining the right inputs avalaible?
Best regards

I ran into a similar problem with this in TRNSED the other day: I wanted to give the end-user the option of using one of two modes for the Type16 radiation processor, and as it turns out these two different modes had a different number of parameters or inputs. Fortunately, I work with the Trnsys savvy, David Bradley, and he contrived a solution. Implement both of the components in the input file, then when the user selects either component (in your case checks a box), it will turn on or off the appropriate outputs of the appropriate component in an equation. Here is a simple example.
I have two different Type16 in the input file. In mode 1 is Unit 2 Type16, and in mode 2 is Unit 22 Type16. When the user selects the mode 1, I set a variable to 1 (RM1=1) and set the other variable to 0, (RM2=0). Then I simply make an equation for the output of consideration that has both of the outputs from both of the components with the variable's "swi tch" to enable or disable that appropriate output.
EQUATIONS 1
QTotSurf=[2,7]*RM1+[22,7]*RM2
Best regards,
Matt Duffy
