Localized Leakage with Dampers

[CliveFirst1234]

Hello,

For a case, I use a HVAC module with a TYPE_ID='LEAK' to caracterize a relatively small opening. I defined the duct length, and the two VENTS according to the User Guide and I wonder if it was possible to use a DAMPER to activate the HVAC module after a small amount of time ? The DAMPER worked with a HVAC defined with TYPE_ID='DUCT', but is it possible with the TYPE_ID='LEAK' ?
Thanks for your time, Regards.

Also, I have a similar case with a HVAC module (type DUCT) and I want to transfer particles through it. I activated the TRANSPORT_PARTICLES=T on the HVAC line (with DUCT_INTERP_TYPE='NODE1', N_CELLS=200) and HVAC_MASS_TRANSPORT=.TRUE. on the MISC line but it seems like it's still not working. Do you know how I could fix this issue ?
