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
