Old postprocess results format

This file is a complete list of the dumped results, where each result will be organized as follows:

Set 1: Header. Results description

The total number of lines in this set is 1, composed of 1 character string, 1 integer, 1 real, 1 optional character string, which depends on the first integer, plus 3 integers:

descr_menu load_typestep_val [load_desc] data_typedata_locdesc_comp ["gauss_points_name"]

where:

Set 2: Description of the components

The description of each one of the result's components, without ant blank spaces, should be entered here if needed, one per line. The number of lines will be as follows:

This description will appear in different menus to select the variable to be displayed at each stage.

Note: GiD also supports 2D results types, so description components can be two for vectors, and three or four for matrix and plane strain analysis, respectively.

Set 3: Results

The total number of lines in this set is the total number of points if data_loc = 1 or the total number of elements multiplied by the number of Gauss points per element if data_loc = 2. The definition of the results is itemized below.

i result[i]

where:

i result_x[i] result_y[i] result_z[i] result_m[i]

where:

i result_Sxx[i] result_Syy[i] result_Szz[i] result_Sxy[i] result_Syz[i] result_Sxz[i]

where:

i result_Si[i] result_Sii[i] result_Siii[i] result_Vi_x[i] result_Vi_y[i] result_Vi_z[i] result_Vii_x[i] result_Vii_y[i] result_Vii_z[i] result_Viii_x[i] result_Viii_y[i] result_Viii_z[i]

where:

i euler_ang_1[i] euler_ang_2[i] euler_ang_3[i]

where:

Note: For Matrix and PlainDeformationMatrix results, the Si, Sii and Siii components are calculated by GiD, which represents the eigen values and vectors of the matrix results, and which are ordered according to the eigen value.

Results on GaussPoints: When defining results on Gauss Points using the new Gauss points format, i.e. giving a "gauss_points_name" to the Result's Header description, the results should be given on a per element basis specifying the element number only once. For instance,

assuming a three gauss point set named "GaussTriang" has been defined over triangles, and there are only two triangles, then a supposed 'Displacement' result will look like this:

GaussDISPLAC. 2 1 2 2 0 "GaussTriang"

5 0.1 -0.1 0.5

0.0 0.0 0.8

0.04 -0.04 1.0

6 0.0 0.0 0.8

-0.1 -0.1 0.5

-0.04 -0.04 1.0

Gauss Points (Old format)

Note: Here is a description of the old Gauss Points file format for the old results file format. However, the new Gauss Points file format (see Gauss Points ) is also compatible with the old results format.

Gauss Points : For the Gauss points to be included in the results, they must be treated as if they were a type of result, but:

- they must be inserted at the beginning of the file; and

- the header structure is the same as that of the results files, but the meaning changes.

Note: GiD can only support Gauss Points on Lines, Triangles and Quadrilaterals, as well as one Gauss point for Tetrahedra and Hexahedra, at the same time.

Set 1: Header. Gauss points

The total number of lines in this set is also 1, but now it is always composed of one character string, one integer, one real number plus three integers:

descr_menu load_type step_val data_type data_loc desc_comp

where:

Note: This must be constant for the whole geometry.

Note: Tetrahedra with 4 or 10 Gauss Points and Hexahedra with 8 or 27 Gauss Points are not functional and are still under development.

Coords_P_Gauss 0 3 0 0 0 1 0.5 0.0 2 0.5 0.5 3 0.0 0.5

These are also the ones that GiD uses internally to calculate Gauss Points for Triangles with three Gauss Points, when this field is set to 1.

Gauss Points positions of the quadrature of Gauss-Legendre for Triangles and Quadrilaterals

This field has no relevance for lines, and should be set to 1.

This field has no relevance for triangles, quadrilaterals, tetrahedra and hexahedra.
