[esp-r] Re: Perl script

My preference for changing geometry would be to alter coordinates in the geometry file directly using sed. This in my opinion is simpler than going through the interface or a script. Also simulation results could be outputted in xml format and interrogated using a style sheet. This method is more robust than scripts because an interface change makes the script out of date.

Given the description below it would probably make more sense
to create the base case model using the standard interface
(graphic) facilities of ESP-r and prove that that initial model
works and that the predictions are ok.

Then (recording each step) the keystrokes needed to navigate the
interface to the required zone and then edit the vertex X Y Z values
associated with the window and save and exit (this would be one
script).

Another script can be used to invoke a standard simulation
and another script can be invoked to extract specific performance
data. The invoke standard simulation and extract results scripts
could be based on the TEST SIMULATE.wc ANALYSE scripts
that are found in the validation/benchmark/QA/model_1.1/cfg
folder.  To get a feel for this go into that folder and type in
the command ./TEST and watch what it does.

One invokes scripts from a standard graphic terminal.  Scripts
would, of course, have to be given execute attributes via an
operating system chmod command.

Thanks Jon, now I'm more clear,

I think working with the text mode and calling the menus with their characters should be more than enough.
But specifically, how do you call that commands with Perl (or the C shell)? could you give me a short example?
For example, how write and run a script that draws a thermal zone and place a goup of windows with a for loop.

I'm working in something like this:
-create one 10x10x10m zone,
-place one 1x1m window,
-simulate and read the thermal data,
-move the window 1m in a random direction
-simulate, and if better maintaind or else go back.

The idea is to automatize this algorithmic process in order to increase its complexity later, but I'm stuck at the basics.
I'll take a look to the developers API, I'm looking for a software flexible enough to code some small procedures combining geometric changes & simulation/evaluation and ESP-r looks perfect.

Regards

Victor

There is perhaps a misunderstanding about how scripts drive esp-r modules.

ESP-r modules can be invoked in a text-only mode and each of the menus that
would normally be seen in the graphic mode are selected by a single character.
Essentially, if you can do a task in ESP-r manually what you want to do is
to capture the sequence of key strokes you used and embed them in a script.

These scripts are not invoking a 'method', they are navigating the interface and
driving the interface to do a specific task (which should work as long as the interface
does not change).

So first become familiar with the ESP-r interface.  It is possible to create a model
from scratch via commands and it is possible to take an existing model and
alter aspects of the model via commands.  And before going to all of that trouble
it would be useful to consider what the other options are.

There is a so-called META file which is a somewhat compact text file that some 3rd party
software uses to pass information about building to ESP-r.

The ESP-r Developers Guide includes an API for ~hundred subroutines and lots of
other information that might be helpful to you.

What is unclear is the big picture of what it is you are trying to do and your goals.
If you could provide an outline then it might focus the discussion.

Thanks for all the feedback, its helping me a lot.

I have a couple of more basic questions, I'm not used to ESP-r scripting "environment" (I come from other software with embedded scripting functionality, like ecotect or rhino). I have noticed that many of the scripts use the C:\ shell, but I have a couple of problems to advance in that path.
First, I don't know how to run the software's commands, is there any document with the methods or an API guide? for example if I want to create a zone, how do I call that method from inside the shell?
The other question regards the possibility to write longer code, for example: create a zone, then 10 windows, assign material, etc... all in one block. I think this should be done in Perl (or Python) but I don't know how to run it and connected to ESP-r methods.

Thanks again,

Victor

Some instances where scripts have been used in the past:
1. ESP-r modelling of domestic heating systems (ADEPT2 available from
sesg.strath.ac.uk<http://sesg.strath.ac.uk><http://sesg.strath.ac.uk>) has scripts that simulate and list the results into csv
files that are readable by spreadsheet macros.
2. Simulation of test models that simulate and write out results in pdf
format. These are used for running comparison tests periodically and writing
out a nicely formatted report.
3. Running regression testing that involves subversion commands, forcheck,
compilation, simulation, results analysis and some other software testing
tasks. (Available at
https://espr.svn.cvsdude.com/esp-r/trunk/tester/scripts/)

The first two use bash and c shell scripts the last one uses perl
