Sectionwise Data Format
The following table shows the format for results data stored as node coordinates, elements, and corresponding data values:
Table 9-4:
Nodes, Elements, Data.
Section
No. Columns
Description
%Coordinates
1–3
One to three columns containing x, y (optional), and z (optional)
%Elements
3 (2D), 4 (3D)
Triangulation where each row contains the row indices of the points in the Coordinates section that make up a single element — triangular in 2D, tetrahedral in 3D
%Data
1
Column of data values
This format can also be used to import data for unstructured interpolation. It has the advantage over the
Spreadsheet Data Format
in that it also contains the exact mesh used to perform the interpolation.
Duplicate values (that is, evaluations with the same coordinates and the same values of the evaluated expressions) are removed before the sectionwise data is exported to file.
