Radiant Variable Flow

Developing an HVAC system with Radiant variable flow panels. I get the following two severe errors which cause the simulation to fail:

** Severe ** ZoneHVAC:LowTemperatureRadiant:SurfaceGroup flow fractions do not add up to unity for ZONE HVAC LOW TEMPERATURE RADIANT VARIABLE FLOW 1CEILINGS
** Severe ** ZoneHVAC:LowTemperatureRadiant:SurfaceGroup = ZONE HVAC LOW TEMPERATURE RADIANT VARIABLE FLOW 6CEILINGS does not have any surfaces listed.

Any idea how to ameliorate these errors? Is there a need/way to specify surfaces in the model for the radiant surface?

@Elliot_Glassman Maybe you should follow this example created by @chris.

@Elliot_Glassman in @chris’ example, it shows you how to create a construction with radiant surfaces, and this method has already tested with Ironbug, which also will help to automatic fix radiant construction issue in multi-floor buildings.
