Tables are supported for both 2D and 3D analyses in Mechanical with the following limitations.
Supported Variables for 2D and 3D Tables
The dimensions of a table's spatial coordinates and pressure components correspond to the dimensions of the analysis. When you create or import a table, the available variables depend on the analysis type you selected. The following table shows which variables can be included in tables for 2D and 3D models:
Table 14.1: Variables for 2D and 3D Tables
| Variable | 2D | 3D |
|---|---|---|
| X_Coordinate | ✔ | ✔ |
| Y_Coordinate or Theta_Coordinate | ✔ | ✔ |
| Z_Coordinate | ✔ with limitations. See Spatial Coordinates for 2D and 3D Tables. | ✔ |
| Time | ✔ | ✔ |
| Temperature | ✔ | ✔ |
| Pressure | ✔ | ✔ |
| Pressure_i | ✔ | ✔ |
| Pressure_j | ✔ | ✔ |
| Pressure_k | ✔ |
Spatial Coordinates for 2D and 3D Tables
If the table contains spatial coordinates:
X_Coordinate and Y_Coordinate or Theta_Coordinate may be present in a 2D model.
X_Coordinate, Y_Coordinate or Theta_Coordinate, and Z_Coordinate may be present in a 3D model.
Warning: Under certain conditions, a 2D model could contain tables with X, Y or Theta, and Z coordinates. For example, you could add a table via scripting or create a table in a 3D model, exit Mechanical and switch to a 2D model in Workbench, then reopen the model in Mechanical.
If a 3D table is assigned to a boundary condition in a 2D model, the Mechanical APDL solver will interpolate to find the dependent variable values for X and Y or Theta at Z = 0. The solver will use these interpolated values when it computes the solution.
Required Pressure Components
If the table contains pressure components:
Pressure_i and Pressure_j must be present in a 2D model.
Pressure_i, Pressure_j and Pressure_k must be present in a 3D model.
If a required pressure component is missing, the table is under-defined. It cannot be assigned to a boundary condition. If the table was already assigned to a boundary condition, an error condition displays in the boundary condition Details pane and the solver cannot compute a solution.
Warning: Under certain conditions, a 2D model could contain tables with Pressure_i, Pressure_j and Pressure_k components. (For example, you added a table via scripting or created a table in a 3D model, exited Mechanical and switched the model to 2D in Workbench, then reopened the model in Mechanical.) The Mechanical APDL solver ignores Pressure_k when it computes the solution.
