RE: [EnergyPlus_Support] Energy+.IDD

You could easily run multiple instances of
EnergyPlus now--running them in separate
directories where the temp and output files will
reside.  You don't need separate executables,
just a local copy of Energy+.ini in the directory.

For example, you can set the directories for this in
the RunEnergyPlus.bat file--telling the program where
to look for (directory), the input and weather files.

Hi

Probably I confused things a bit.

2. I don't have the source code or I don't have access to it. I was
thinking (just a thought) if EnergyPlus could be recompiled (I didn't
want to, even if I wanted, I would get a developer license) and the
options were set such that multiple instances could be allowed in the
function calls of the source code - might solve this particular problem;
provided that I assumed - E+ developers didn't want to allow multiple
instances.

One of the problems I faced when developing ArDOT is that EnergyPlus
only allows one instance of the application per machine. I assume that
EnergyPlus makes some temp files like in.idf while running a particular
simulation. Running multiple instances (after recompiling E+ and
allowing multiple instances) at the same time may create file access and
permissions problems. The problem is acute, when somebody wants to run
EnergyPlus as a server.

1) this discussion would be more pertinent for the EnergyPlus Developers
list

2) I do not have anyone in Ireland nor your email/name listed as a
collaborative developer.  How did you get access to the source code and
"re-compile"?

3) Energyplus can run more than one instance but you have to set the
"working directory" accurately -- that would be an interface problem to
solve rather than trying to do something os-dependent from within
Energyplus.
