Jens,
My guess is that you may need to look at the section of Type534
that reserves space in the global output and storage arrays. Space is
reserved in the OUT() array by setting INFO(6) and then calling
TYPECK() at the start of the simulation. Space is reserved in the
global storage array by calling the SetStorageSize() subroutine. The
problems that you describe sounds like what happens when one
component overwrites the outputs of another.
Kind regards,
David

Dear all,
I'm using the type 534 storage tank of the TESS libraries. I made a
small change in the code, I set the maximum number of ports to 20.
Beside other components I use an online plotter with file to see and
print the tank nodal temperatures. The system runs ok, but if I
change the double port of the solar circle I get an invalid floating
point operation error. This happens only if I have the respective
plotter switched on and the tank energy balance error connected to
the plotter. As soon as I switch off the plotter or disconnect the
balance error everything is alright. In the output file of the
plotter I get normal values for the balance error and at some times
it is written "NaN". Those are probably the times where I get the error.
This is no problem for me as I don't necessarily need the balance
error and so I don't need real help from you. I am just curious what
the reason might be and if anybody of you ended up with the same behavior.
Thanks for any replies
