Thanks, @MingboPeng.
I’ll remove the dumpHBObjects component for the time being as suggested.
Yes, the IDF file contains everything. However, the IDF importer component in HB currently has limitations, and @chris as recommended using the load/dump HBObjects components:
IDF importer component does not correctly identify the air walls
Theoretically, if I do want to dump the HBObjects for all the cases, I can use the iterator to drive it solely and separately so as not to interfere with the simulation workflow. What do you think?
