I have several chilled ceilings in a complex office model.
Using Designbuilder I had no problems in Energyplus v7.2 or 8.1.004 beta.
Using the new Designbuilder version with Energyplus v 8.1.008 I get 4 severe errors regarding nearly zero fractions in a chilled ceiling surface part.
Energyplus advises me to remove these surfaces, but in Designbuilder you can't do this. Anyone ayn idea what suddenly causes this error ?
************* Beginning System Sizing Calculations
** Severe ** The Flow Fraction for Surface 2RECHTS:NIVEAU2RECHTS_CEILING_1_0_22 in Surface Group 2RECHTS:NIVEAU2RECHTS CHILLED CEILING RADIANT SURFACE LIST is zero
** ~~~ ** ...Zero flow fractions are not allowed. Remove this surface from the surface group.
