Apologies if this is stupid question, but when modelling a building do I have to model the internal doors?
I only ask as I am modelling a 200 apartment extracare facility and at present I have not input any internal doors. Will my macroflo results be incorrect if I do not set up these doors.
If I must model them, how should I approach the crack flow coefficient and the profile? I have no idea how to approach the opening profile!
If I do model the doors, as a worst case one should assume the doors are always closed. If I set them to always closed is there any point including them?!
Any help would be greatly appreciated! Thanks.

Re: Modelling Internal Doors
I don't think it's a case on your results being incorrect just marginally less accurate.
if you expect the doors to be closed i don't think this is going to make a world of difference to your results.
Assuming temperatures either side will be similar, as this is an internal door, any difference in conduction will be minimal
Crack flow coefficients are typically between 1.1 to 2.0 for an internal door but again this isn't a large flow rate.
Only when you start opening the doors will it make a bigger impact
Often it's best to simulate an example room(s) to help you decide the impact in cases like this.
