[EnergyPlus_Support] Re: IMF files & EP Macro

Hi Jeremiah,

Did you get it to work?

1) Macro functionallity
I don't know Je+. What Linda described as a dummy imf is what I usually use. The imf is "expanded" into just one idf. That means, every txt file that you "include" is written into the same idf. I don't think this is right for you.

2) How I think Je+ works
Having absolutely no idea, I suspect that Je+ wants an idf with everything in it except your PCM object block of code. Then you have that PCM object block of code loaded into the idf. For each parametric run Je+ loads a different PCM block of code. So I think all that Je+ needs is the txt files to be ending with imf and one "master" idf (possibly with imf extension) with all the other normal code in it.

3) Alternatively, e+ has a parametric preprocessor. You can define a parameter as 
Contruction, PCM,         ! object , object name 
$MyParameterObject,      ! field 1 
bla bla,                 ! field 2
bla bla,                 ! field 3
bla;                     ! field 4

and then a parametric object which describes how many times and what you want to change this...something like

ParameterObject,
MyParameterObject, !parameter object name
myFirstPara, Field 1
mySecondPara, Field 2
my3rdPara; Field 3

What happens is e+ then makes 3 distict idfs where $MyParameterObject is using myFirstPara in the 1rst idf, and mySecondPara in the second and so on.

You'll have to check the syntax...I'm just making this up so you get the idea.

Then from eplaunch you can run these simulations and it will run as many in parallel (one simulation for every available processor on a multi-procecor computer).

I suspect Je+ does something similar and somehow mixes the macro and parametric functionallities, where the parameter object is not possible in the macro dummy file as the parametric preprocessor runs only after macro and idf expansion.

Let us know how you get on.

Regards,

Jean
