Re: [TRNSYS-users] Time Inconsistency!

[David Bradley <bradley@tess-inc.com>]

Davide,
When you specify your simulation time step in the Studio, I assume that 
you are changing the units from hours to minutes and then entering the 
corresponding value. What I would recommend is that you set the 
simulation time step units to "string" and enter the variable name "DELT"

Next, in the field at the bottom of the control cards window, paste the 
following two lines:

EQUATIONS 1
DELT = 10/60

(if you want to run with a different time step - 5 minutes, for example, 
then make the equation

DELT = 5/60

TRNSYS is trying to find two integers that when divided, give a value 
that is as close as possible to the decimal time step that was set. The 
Studio has a tendency to truncate time steps that are not entered in 
units of hours when it converts them back.

Kind regards,
David
