[TRNSYS-users] number of hx pipes in type 713



Hi, I have a problem in type 713 when a want to add more than one HX pipe. The fatal error is:

TRNSYS Message     99 : Bad or missing data on control card. 
> TRNSYS understood a keyword and is looking for additional 
> information for that keyword, but cannot find it. The control card 
> is in "reported information" below.
>     Reported information  : ASSIGN "pipe713.dat"
>
>ASSIGN "pipe713.dat"

I suppose that if the number of HX pipe is greater than one, I have to add an external data files for each pipe, but the model generates the same logical unit number and it only allows to introduce one external data file. I try all the possibilities, I change the proforma of type 713 to allow introduce more data files and I describe the pipe configuration in one data file, but the error is always the same.

I would like if someone have had the same situation and if have found a solution.

Thank you.
