This section describes the format of the ASCII text files that can define the relationship between pressure and flow rate for all of the 3D fan cell zones in a case file, as described in 3D Fan Zones. The following is an example of such a file:
cell zone id 17 !CELL_ID Pressure(Pa) Flowrate(m3/s) -324.0 1.255 -215.0 1.162 -109.0 1.032 0.0 0.997 63.0 0.913 105.0 0.862 302.0 0.584 394.0 0.492 406.0 0.432 443.0 0.365 cell zone id 18 !CELL_ID Pressure(Pa) Flowrate(m3/s) -333.0 1.130 -215.0 1.122 -165.0 1.064 0.0 0.981 42.0 0.912 90.0 0.855 112.0 0.786 303.0 0.546 344.0 0.492 395.0 0.451 411.0 0.399 442.0 0.324
When creating or editing a file that defines the 3D fan zone curve, note the following:
The file can be created from nothing using a text editor or spreadsheet program, as long as it adheres to the format described in this section.
The file must be a tab-delimited ASCII file.
A single file can define multiple cell zones, but it must be read in each of the applicable Fluid dialog boxes.
For each section that defines the curve for a cell zone, the first three lines must follow the convention shown in the previous example, and then each of the subsequent lines must list the experimental results.
The zone IDs (for example,
12) must correspond to those that exist in the intended case file.The units must match those in the case file.
