no position, then How is the ideal heating operating or working? How
to observe its operating or working way etc.?<BR><BR> Because although I

<DIV><FONT size=2 face=tahoma>Thank you for the reply. The EES project
was defenately openening and closing, but EES itself stayed open. I
fixed this problem now with changing the pad for the
EES project from</FONT></DIV>

<DIV><FONT size=2 face=tahoma></FONT> </DIV>
<DIV><FONT size=2 face=tahoma>But now it seems that EES-TRNSYS
coupling has a limited number of outputs, is this correct? When I
run a long simulation with alot of timesteps, the simulation stops after
a while, I think it is after 66000 timesteps with 20 inputs and 40
outputs with the EES-TRNSYS coupling. Is there a solution for
this?</FONT></DIV>

<DIV></DIV>
<DIV>Joris,<BR> It isn't actually the opening and closing that
takes time (EES stays running the whole time). The slowness is the EES
calculation time and the fact that EES is called at every single
timestep and at every single iteration within a timestep of your TRNSYS
simulation. There are a few different versions of Type66 that allow you
to avoid calling EES whenever possible (basically an input that is an
on/off switch for the EES calculations). If you know that your EES
program doesn't have to be called (because the device that it models is
inactive) then you can "turn off" the call to Type66 and save some time.
Take a look at the EES example in the ..\TrnsysXX\Examples\Calling_EES\
directory; all the different options are shown in there.<BR>Kind

defined these variables as:<BR><BR>T_min=65<BR>T_max=80<BR>T_out=

have plotted the signal. It works fine but I am experiencing a
very long simulation time. More than 15 minutes just for a
week.<BR><BR>Is there any
idea?<BR><BR>Thanks,<BR>Shahrdad<BR><BR></SPAN></P></DIV></DIV><BR>_______________________________________________<BR>TRNSYS-users
