CFD tab of model options
This tab allows you set various types of boundary condition for CFD calculations.
If you have previously loaded simulation results as boundary conditions using the CFD Boundary Conditions Edit dialog then this data will be displayed at surface and opening levels.
The attributes that can be set on this tab are shown with the boundary condition type to which they apply. Note that all attributes are displayed at zone level and above in the hierarchy because these act as defaults, but at surface and opening level only the data applicable to the current object is displayed.
Note: Data specified on this tab does not affect EnergyPlus simulations
Applies to: Internal surfaces, doors and sub-surfaces
Default inside surface temperature for internal surfaces (partitions, internal floors and ceilings). It can be set for all levels in the model hierarchy from building level down.
This value is also used for virtual partitions to represent the average temperature of the surfaces in the adjacent room.
Applies to: External surfaces, doors and sub-surfaces
Default inside surface temperature for external surfaces (walls, roofs, external floors etc). It can be set for all levels in the model hierarchy from building level down.
Applies to: Internal and external windows
Default inside surface temperature for window surfaces. It can be set for all levels in the model hierarchy from building level down.
Applies to: Zone
Average zone temperatures are stored at zone level. These aren't used yet in CFD calculations yet but will be used in checks in a future version to ensure equal convective heat gains are considered in the CFD and EnergyPlus simulations.
Applies to: Supply diffusers (types 1-3) and windows, vents, doors and holes
Temperature of air entering the space through windows, vents, doors and holes.
Data on this tab is also used for entering boundary conditions for component blocks, assemblies and for boundary condition patches drawn onto zone or component block surfaces. For details see:
