Ive recently been trying to add HVAC systems to a model with components that don’t exist within ironbug using the addstring option on the model to OSM component. It seems that many of the issues im facing would be made much simpler if the txt string was able to overwrite existing sections of the ladybug/OSM generated IDF such as node names and zone names, zone equipment lists etc of the IDF that are contained within it.
I’m also trying to figure out if there is a way to run an IDF file through ladybug tools in order to create an OSM with it to visualise the HVAC system it contains.
has anyone else tried this/ have any pointers?
specifically i’m looking at desiccant dehumidifiers
I have the same problem like yours, what I do, is to open the .osm file using Openstudio Application that is free available on the Openstudio website, then I detect the challenges I have such as nodes integrity and components, branches, and demand and supply sides.
for this purpose also instead of having a Boolean button to the run input, if you connect 2 and 3 in a pallete as text to the _run, it will not run the whole simulation that is time consuming and it will creates the .OSM file for you to detect the issues.
Thanks for the reply. I have been doing this which works well except that neither open studio or ironbug have the components i want to use so i must first write them in IDF
if you find something in the OpenStudio that still not developed in IB/LB/HB, you can post that here in this forum with the OpenStudio .osm example, Lady Bug developers will developed that. I tried this many times and @chris and @MingboPeng did that perfectly.
