Where to set HVAC_MASS_TRANSPORT_CELL_L?

[IFAB-AS]

Hello,
We want to use the HVAC_MASS_TRANSPORT_CELL_L feature, which assigns the same cell length (approximately) to all ducts within a HVAC system. Where do we have to specify this? Section 10.2.8 in the User Guide does not say this.

I tried it on the duct line itself, but this does not start and gives an error message. On the &MISC line it does start but crashes with FORRTL SEVERE error after a few seconds.

Thanks for pointing out the Guide issue. It goes on &MISC (which is why you didn't get an input error when you put it there). Can you attach a simple input that demonstrates your runtime error?

I did test it with a different fds file, there it seems to work when using the &MISC line. The attached test file gives the forrtl: severe (157): Program Exception - access violation' error:
VENT_Test.txt

Should be fixed now. Your case now runs to completion.
