Field functions provide a mechanism by which fields (raw data from the simulation stored in the cells and/or on the boundaries) may be viewed and defined in STAR-CCM+. Available field function nodes may be viewed in the Field Functions manager node under Tools in the object tree.
All field function nodes are subject to common menu items, but their properties vary by type. The most common set of properties is for the primitive type.
Once the field function has been made available, it will be provided in scalar and/or vector drop-down lists for any operation that needs to access them, notably visualization, XY plotting, reporting, monitoring and creating table data.
The field functions may be classified based on the following:
Field functions can only be accessed on a part if the data used to define the field function exists on that part. For the data to exist it must be allocated on the specific part and must have been initialized. For example, wall shear stress is a quantity that is stored only on walls in viscous-flow simulations. Therefore the wall shear stress field function, and related field function quantities such as Wall y+, can only be displayed on wall boundaries, and only after the solution has been initialized.
