<p><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">Hi,</span><span style="FONT-SIZE: 10pt; FONT-FAMILY: Verdana"></span></p>
<p><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">I am modeling a large welcome gallery of a museum using </span><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">IES</span><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">
/VE v5.8.1. </span><span style="FONT-SIZE: 10pt; FONT-FAMILY: Verdana"></span></p>
<p><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">When I try to run the MicroFlo CFD simulation (after running Suncast, Apache, i.e. following all the steps required before running a CFD simulation in </span><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">
IES</span><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">), I get a 'Unbalanced Flow' prompt that gives a subtraction of two cfm numbers and it states that 'in-flow and out-flow must balance'. </span><span style="FONT-SIZE: 10pt; FONT-FAMILY: Verdana">
</span></p>
<p><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">This happens before </span><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">IES</span><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana"> runs any CFD simulation. I tried to change the number of operable windows both in lower levels and higher levels of the space and every such change results in different cfm numbers being subtracted in the prompt and it does not run any simulation.
</span><span style="FONT-SIZE: 10pt; FONT-FAMILY: Verdana"></span></p>
<p><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">The space I am trying to analyze is conical in shape with the height of ~50 ft (15.24 m) and has a base of 64 ft (19.5 m) diameter. I modeled this space first as 3 different spaces- the bottom being the widest and it becomes narrower as it goes higher and then I used the 'connect spaces' command to connect the three spaces without any partitions.
</span><span style="FONT-SIZE: 10pt; FONT-FAMILY: Verdana"></span></p>
<p><span style="FONT-SIZE: 11pt; FONT-FAMILY: Verdana">Any thoughts on what's causing the unbalanced flow? and how can it be corrected? Is it due to the grid settings? I am just making a trial run and have not yet detailed the model much and left almost everything to default.
