Re: [TRNSYS-users] Trnsed and parameters cycle

Dear Thibaut,

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 "sw! itch" to enable or disable that appropriate output.

EQUATIONS 1
QTotSurf=[2,7]*RM1+[22,7]*RM2



Best regards,

Matt Duffy

Subject: [TRNSYS-users] Trnsed and parameters cycle

Dear Trnsys users,

I'm creating a trnsed application, and I need to define walls for a 
simplified building. I'm having difficulties to program a cyle for 
parameters. I've tried to use a model with a cycle implemented in the 
tmf, but it does not work, and if I understand well how trnsed works, it 
seems normal.

So I tried to make one using check box group that ask how many walls 
need to be inputed. But it is not what we can call "user friendly" since 
a numerical value would do the trick with a lot of space spared.

So my question is : Is it possible to take into account tmf cycles, or 
is it possible to make it with a numerical value, or does anyone have a 
good tip to share? I've looked into the applications I've found on the 
web, but I did'nt found anything relevant. (If you have a good example 
of an application using advanced trnsed possibilities that is avalaible, 
even if it does'nt answer my question, I would be happy to have a look 
!!! )

Many many thanks in advance.

Thibaut
