Hello, I'm having a problem with my OS model that has zone WSHP. See attached photo below. When I ran the model, I received this error message below and I don't know to fix it. * Severe * PsyRhoAirFnPbTdbW: RhoAir (Density of Air) is calculated <= 0 [-8.48360E-019]. * ~~~ * pb =[93779.00], tdb=[-2.44E+020], w=[0.3583424]. * ~~~ * Routine=Unknown, * Fatal * Program terminates due to preceding condition. ...Summary of Errors that led to program termination: ..... Reference severe error count=11 ..... Last severe error=PsyRhoAirFnPbTdbW: RhoAir (Density of Air) is calculated <= 0 [-8.48360E-019].C:\fakepath\2016-10-18 18_20_01-Proposed_Start_20161018.osm.png
Any help would be greatly appreciated. Thank you. PM
