Table fields

Table fields let you use tabular data to define the relationship between the independent and dependent domains. The tabular data is interpolated or extrapolated to obtain values for the dependent domain at values of the independent domain where a data point is not defined.

Depending on the application for the table field, the actual interpolation and extrapolation may be performed during pre-processing or by the FE solver during the solve.

To create a table field, you define the independent and dependent domains, and then enter the tabular data. Tabular data can be real or complex.

You can use table fields to define:

• Boundary conditionsFor example, you can use table fields to define the magnitude and, if applicable, the distribution of the boundary condition.

• Material propertiesFor example, you can use table fields to define how a material property varies with respect to temperature, strain, or temperature and strain.

• Material thicknessFor example, you can use table fields to define how the thicknesses of sheet bodies or shell meshes vary spatially.

• Physical propertiesFor example, you can use table thickness to define how the axial or rotational stiffness of generalized plane strain elements vary with time.

• Mesh size informationYou can create a specific type of field, called a Mesh Size Field to store element location and length information from an existing 2D or 3D mesh. You can then use the field to apply the mesh size data to a different part. For more information, see Refining a mesh using field data.

Note:

As a best practice, when the independent domain of the tabular data contains both spatial variables and a non-spatial variable, to minimize interpolation error, use a table of fields rather than a table field. For more information, see Table of fields.

The following figure shows how a table field can be used to define the distribution of a force along an edge.
