Dear TRNSYS users, I am currently running simulations on
TRNSYS, being 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 |
