Hello,
do you have idea how to simulate air flow of duct and then use results to simulate air flow in the room?
Attached picture is basic sample - real duct is complex and I'd like to do separate calculation with high level for mesh and then take results (velocity profile on surface) to put them into room analysis.
More - on the duct outlet(s) I'd like to use perforated plates which now can be used on pressure openings
Any idea?
Kamil
BTW. Ansys has no problem with that.
Unfortunately you cannot do that. The only transfer of filed values from one model to another is the transfer of the Initial Data. You can also export the hydrodynamic forces to apply as loads in the Simulation Solver by Tools/Flow Simulations/Tools/Export Results to Simulation (the transfer is internal - no external file is created).
A work around (but not exact transfer) is to approximate the data at the duct outlet by a function, and then use that function (formula) in the formula definition of the boundary values.
Hello,
that's what I afraid of.
ER will be created for that.
Thank you!
Hi Kamil, I checked this capabilities with SW2017 Beta. As a result of numerous Users request for the same Enhancement in the last 3-5 years it is already implemented. See Tools/Flow Simulation/Insert/Transferred Boundary Conditions.
Hi, I've checked - this functionality was there before 2017 Beta but it is not applicable for that case or I do not familiar with it.
My VAR has given me some example but it's different.
Next days I'll try to test other CFD software and I'll share effects.
Thanks
Hi Kamil. I am with SW2015 and the enhancement probable was implemented in the following versions.
If the coordinate system is the same in both Models (the duct model and the room model) then you just need to select the Inlet surface (outlet for the Duct Model) in the Transferring BC panel, and to point to the result file of the Duct Model. It should work. I have not tried it yet with SW2017 Beta.
