For your example, the HVAC network would contain a single zone where you want to add mechanical supply. The upstream side of this zone would have a flow controller set to provide the required flowrate and the downstream side would have a flow controller set to zero volume flow, on continuously. With Macroflo and HVAC both active in ApacheSim, the mechanical supply will be introduced, as defined in the HVAC network, and Macroflo will calculate what subsequently happens to that air (provided there are sufficient Macroflo openings to prevent the run crashing due to overpressurisation). Hope this helps.</span><span lang=EN-GB><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-GB style='font-size:10.0pt;font-family:"Segoe
