Re: [EnergyPlus_Support] parametric runs
When setting up macro-based (imf) parametric runs, it is helpful to test the
imf file by setting "counter" to a value and running as a single run:
##set1 counter=1
Next, review the epmdet file for macro processing errors. Note that errors in
the ep-macro logic do not get passed on to the main EnergyPlus .err output
file. They only appear in the epmdet output file.
Next, review the epmidf file to see what the final input stream is.
It can also be helpful to add this command at the top of the file:
##showdetail
This shows the details of how every macro variable is expanded (in the epmdet
output file).
In this particular case there are the following problems:
1. in the ##set1 commands, there should not be [] on the variable names on the
left-hand side of the equals sign. These lines should look like:
##set1 wintype = w001
(But this doesn't appear to be causing a problem.)
2. There is an error in the elseif command for case 5, so I am suprised that
you are getting any output at all for any case after 4.
##else if #[counter[] eq 5]
There are other occurences of "else if" also that need fixing.
Should be "elseif". There are errors in the epmdet file regarding this.
3. EP-Launch says there are 64 runs because it is counting the blank lines in
the epg file. If you watch closely, you will see that it skips quickly past
the even numbers and only does a simulation for 1,3,5, . . . I will submit a
bug report to fix this.
4. Now I see why you are getting the same results for every run. If you check
the epmidf files, I think you will find that all of your results are for case
4. The problem is the fileprefix statement. It needs a trailing "\"
##fileprefix C:\Program Files\EnergyPlusV1-3-0\
So, if you add the trailing \ and fix the bad "else if" lines, it looks like
everything should run as expected.
