Dear TRNSYS users, I am currently running simulations on
TRNSYS, which is connected to an EES
calculation (Engineering Equation Solver) and I experienced some basic but
severe problems. 1.
It seems that there is a maximum
number of EES-outputs, for EES as well as for TRNSYS. EES maximum: in my case, the EES module does not calculate, if
there are more than 53 defined outputs (found out by trial&error). TRNSYS
maximum: the simulation stops after one simulation period if there are more
than 34 variables sent by EES to TRNSYS (found out by trial&error). Thus
one generally has to limit the number of EES outputs. Questions: 1.1.Does this hold? 1.2.If yes, why? 1.3.Can I change or manipulate this?
AND 1.4.If yes, how? 2.
If the simulation is running
(with less than or equal to 34 EES outputs), it is stopped after a time of 158
hours, which in my case corresponds to 3160 time steps. EES seems to stop the
simulation, showing the warnings “Out of system resources” and “CANVAS does not
allow drawing”. Presumably, the reason might be the
clipboard size, which is filled by too many symbols after the given period –
according to EES, there is indeed a maximum of some 65.000 symbols that can be
copied into the clipboard. If this holds, I am asking myself, if this is this
the maximum number of symbols for A) a single copy-operation or B) for the sum
of all copy-operations? Well, A) cannot be true, because I do not have such an
amount of symbols defined as output. But if B) turns out to be true, my
clipboard has to be deleted as soon as it gets full. Then, my questions would
be: 2.1. Can the clipboard be deleted automatically without stopping the
simulation? 2.2. It this is so, how? Thank you for your help, Sincerely yours Mathaeus Nierzwicki |
