Virtual Disk Field Functions
The following field functions are made available when the virtual disk
model is activated.
- Inflow Plane Marker of [virtual disk]
- Marks cells to indicate which volume cell is identified as part of the inflow velocity plane. A value of 1 indicates that the cell is part of the inflow velocity plane. A value of 0 indicates that the cell is not part of the inflow velocity plane. This field function can be used as input to a derived part of the type threshold.
- Indicator of [virtual disk]
- Marks cells to indicate which volume cell is identified as part of the virtual disk. A value of 1 indicates that the cell is part of the virtual disk. A value of 0 indicates that the cell is not part of the virtual disk. This field function can be used as input to a derived part of the type threshold.
- Normalized Span of [virtual disk]
- Displays the normalized radius (values from 0 through 1 where 0 corresponds to the origin of the virtual disk and 1 corresponds to the outer radius of the virtual disk) of cells within the virtual disk with respect to the local coordinate system of the virtual disk.
- Normalized Span Star of [virtual disk]
- Displays the ormalized radius of the virtual disk as given by Eqn. (4978). The values range from 0 through 1. A value of 0 corresponds to the inner radius (at the hub) and a value of 1 corresponds to the outer radius (at the tip) of the virtual disk. The radius is with respect to the local coordinate system of the virtual disk.
- Cell Azimuth of [virtual disk]
- Outputs the angular position of a cell within the virtual disk with respect to the local coordinate system of the virtual disk.
- Virtual Disk Source Term [virtual disk]
- Shows the distribution of the virtual disk source term per unit volume over the disk. This function is only available when Display Source Term is activated on the virtual disk.
User Defined Method Field Functions
These field functions are specific to the user defined method of the virtual disk model. They are made available to access the flow field values to define the volumetric source term through field functions or user coding. You cannot visualize these field functions on the volume mesh cells or on the virtual disk mesh points.
- Normalized Thickness of [virtual disk]
- Displays the normalized thickness with values from 0 through 1 where 0 is at the outer surface of the virtual disk in the negative Z direction and 1 in the positive Z direction.
- User Defined Inflow Plane Density of [virtual disk]
- Outputs the volume-averaged density on the inflow plane for each bucket on the inflow plane mesh. For more information, see Inflow Velocity Plane.
- User Defined Inflow Plane Velocity of [virtual disk]
- Outputs the volume-averaged velocity on the inflow plane for each bucket on the inflow plane mesh. For more information, see Inflow Velocity Plane.
