<p>Mariam,</p>
<p>I caught and fixed this error a few months back and it'll be part of the next TESS Library update. If you'd like the fix beforehand I can show you what lines you have to change in the code. It was a sneaky little issue where FORTRAN struggled with the type of variable being passed to an array.</p>

<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: #000000;">Dear colleagues,</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: #000000;"> I would like to model gaussian noise - white noise - using model Type578, which is supposed to generate normally distributed random numbers given a seed. However, when examining the output of model Type578, what is get is a periodic triangle signal. Is there a way to get noise-like signal in TRNSYS?</div>
