Tables
Tables refer to objects in Simcenter STAR-CCM+ containing tabular data.
All of the tables that are created in a simulation are listed under the node. Tables are multi-variable entities akin to spreadsheets. They can be used for:
- Specifying tabular data for the simulation, particularly for boundary conditions and/or initial conditions. If you are providing table data based on experiment or analysis, for example, material property data, be aware that data organized in a Cartesian manner gives the best performance. See Cartesian and Structured Tables.
- Extracting tabular data from the simulation, for instance to use as boundary conditions for other simulations
The table contains a combination of location and scalar data. Normally, a file table is created using external data such as from experiments or an analysis, but it could also be extracted and exported from a simulation.
The types of table that are available in Simcenter STAR-CCM+ are listed below. For more information on each type and on the available properties and actions, see Tables Reference.
| Note | To import properly into Simcenter STAR-CCM+, an input file that contains special characters (including accented characters) requires UTF-8 encoding rather than ANSI. |
Table Types
| File Table | A file table contains data that
Simcenter STAR-CCM+ imports from a table data file of format
.csv,
.tab, or
.xy.
It is possible to access the table data from a field function. |
| Histogram Table | Histogram tables show the distribution of a selected quantity with optional weighting. |
| Accumulated Force Table | Accumulated force tables provide a convenient way to plot accumulated pressure and shear forces (or both) over the surface of selected parts. |
| Radial Internal Table | A radial internal table
specifies location in terms of radius, and the data set must
contain an identifier specifying that it is a radial table. The
radial internal table also needs a list of identifiers
corresponding to the “columnar data” in the file. The columnar
data must contain the radial coordinate as well as the scalar
data; extraction fails with a warning message if this data is
missing. An example of the file format is given in File Format Reference. The interpolation method for radial tabular data is a cubic spline. Hence, it is assumed that the radial data are sorted and single-valued. |
| XYZ Internal Table | An xyz internal table
specifies location in Cartesian coordinates corresponding to
cell,
face, or parcel centroid positions in the
Laboratory coordinate system. The data set must contain an identifier specifying that it is an xyz table. It also needs a list of identifiers corresponding to the “columnar data” in the file. The columnar data must contain the Cartesian coordinates (x and y are only required for two-dimensional simulations) as well as the scalar data. An example of the file format is given in File Format Reference. The interpolation method for xyz tabular data is zeroth order. When interpolating the data to a specific cell or face location, Simcenter STAR-CCM+ finds the coordinate location in the tabular data that is closest to the specific cell or face centroid. Simcenter STAR-CCM+ then applies the appropriate scalar data from the table to that cell or face. |
| RCR Table | Simcenter STAR-CCM+ Batteries uses RCR equivalent
circuit model parameter tables to define equivalent circuit
battery cells. In an RCR table, each set of Vo, Ro, Rp, and tau parameters are functions of the state of charge (SOC) for a particular temperature. The evolution of each parameter is specified as a column within the RCR table. |
