Reading CLG and HTG files

[dtnuno]

Hello

I've searched the forum and found a post where someone was in need to interrogate HTG and CLG files. Since I am also in need for it and the solution presented in that post didn't work for me, I was wondering if the functionality changed into a new class or stopped being supported.

The solution was something along these lines:

Code: Select all

file_name = IesFilePicker.pick_vista_file([("APS files", "*.aps"), ("HTG files", "*.htg"), ("CLG files", "*.clg")], "Pick a results file")

with iesve.ResultsReader.open(file_name) as results_file_reader:
    assert results_file_reader is not None, "Error opening results file"
    aps_units = results_file_reader.get_units()

However, the output I receive is:

Code: Select all

Traceback (most recent call last):
  File "test.py", line 16, in <module>
    with iesve.ResultsReader.open(file_name) as results_file_reader:
FileNotFoundError: APS file not found: name_of_the_file.htg

Thank you in advance for all the help you can provide

Best Regards

Hi,

Just tried the snippet and it seems to be working ok for me. This is the full script I ran:

Code: Select all

import iesve
from ies_file_picker import IesFilePicker

file_name = IesFilePicker.pick_vista_file([("APS files", "*.aps"), ("HTG files", "*.htg"), ("CLG files", "*.clg")], "Pick a results file")

with iesve.ResultsReader.open(file_name) as results_file_reader:
    assert results_file_reader is not None, "Error opening results file"
    aps_units = results_file_reader.get_units()

Thank you for the reply. I don't know exactly why that file wasn't working but i tried with another htg and it works fine thank you.

On another note, if you could help me with another matter I have at hands, I'd be very grateful

When using the filereader to retrieve the variable list, I can't find any variable related to hvac component. (ie, model level "h"). I'm just trying to confirm if they do appear there since none of the aps files i tried so far, give me any results for this specific model level.

Thank you in advance

They are there as long as you have enabled HVAC component results in the output options when running your simulation.

They are tied to specific components so you need to use get_hvac_component_results().

First of all, thank you for being patient with me.

Yes I will then use the function get_hvac_component_results() along with the ID I got from the hvac network. But even after I made a new simulation with everything ticked in the output options (made sure even hvac components were checked), I still get 0 vars from model_level 'h'

I tried with a few files already and I can see the results in VistaPro but can't get the variables through python API. Would there be something missing still?

Thank you in advance

Best regards

If you can see them in Vista then the variables are available. Is the issue that they don't appear when calling get_variables()? I don't think component level variables are included in the output of that method. However you can still use them with get_component_results().

Yes, that would be correct. The issue is not being able to list/get the variables for the hvac components. As you mentioned, perhaps component level variables aren't included in that method. Would there be any way for me to retrieve that list by another means?

Thank you in advance

@dtnuno did you by any chance have any success in reading the HVAC Component Results in the end? Or at least get a list of the apache HVAC component aps_var names? I am having the same issue and getting an error and I think its due to the variable name I am using.
