I have spent countless hours attempting to run an indoor airflow test to simulate airflow (relatively low volume) for a HRV system and ducting locations.
I cannot seem to get it to run - I face the following issues.
Firstly - snappyhexmesh does not seem to always want to operate correctly (attached file at last attempt would not mesh correctly)
Secondly - when the mesh decides to actually work, sometimes the simulation will fail, it won’t write an openfoam file or something along those lines.
And lastly - when the planets combine and the sim actually runs (currently cannot get this far, without changing parameters the above to issues decided to once again come into play) it seems to only run through one duct outlet instead of the 4 determined, and the extract air ducts seem to not be extracting (at equal pressure in an airtight envelope)
I’ve linked the .3dm and .gh, please any help on this would be greatly appreciated, I’ve lost countless hours over the last month just going round in circles
