Overview

This section describes the format of the individual records in the results file. Where applicable, the output variable identifier used in writing a given value to the file is printed below the corresponding record type description. Records that are available only in ABAQUS/Standard are designated with an ^(S); records that are available only in ABAQUS/Explicit are designated with an ^(E).

Record format

The results file is written as a sequential file. Each record has the following format:

Location	Length	Description
1	1	Record length ()
2	1	Record type key
3, 4...	()	Attributes

All words in the results file are of the same length, whether they contain integer, floating point number, or character string data. The word length is that of a double precision floating point number (8 bytes).

The attributes in a given record may depend on the element type being considered. For example, the stress components associated with three-dimensional shell elements are , , and (in local directions), while those associated with three-dimensional solids are , , , , , and (in global directions if no local orientation is specified). Thus, care must be used in interpreting the data when postprocessing the file output. Refer to Part VI, “Elements,” for a definition of the ordering of element-dependent attributes.

In steady-state dynamic analyses, complex values are stored as the real components followed by the imaginary components. For example, the stress components associated with three-dimensional shell elements are , , and followed by , , and .

In models that are defined in terms of an assembly of part instances, the results file contains internal (global) node and element numbers, as explained in “Output,” Section 4.1.1. Part and assembly records are not included in the results file.

Local coordinate system

If the components of an element quantity are in local directions, a record of type 85 defining these directions is generated for each point at which component output is requested if the local coordinate directions were requested in ABAQUS/Standard (see “Output of local directions to the results file” in “Output to the data and results files,” Section 4.1.2) and automatically in ABAQUS/Explicit. The local coordinate system may be inherent to the element, as is the case in shells and membranes, or may have been defined by a local orientation (see “Orientations,” Section 2.2.5).

For shell elements a direction record is written for every material point in the section for which component output is requested, and a separate direction record is written for section forces and section strains. For geometrically nonlinear analysis in ABAQUS/Standard the record contains the current, updated directions, except for small-strain shells, in which case the original directions are given. Direction output is not provided for trusses, two-dimensional beams, axisymmetric shells or membranes, or for values averaged at nodes.

Label record

Some record types include labels, such as element and node set names, written in A8 format. If a label exceeds 8 characters, an integer identifier will be written instead. This identifier can then be used to cross-reference the actual label stored in 10A8 format on record type 1940.

Records written for any file output request

Record key: 1900 Record type: Element definitions
Attributes:   1  –  Element number.

In ABAQUS/Explicit quadrilateral/brick elements that are degenerate (i.e., possessing identical nodes) are written out in record 1900 as corresponding triangular/tetrahedral/wedge elements. For example, a CPE4R element with two identical nodes is written as a CPE3 element, and a C3D8R element with identical third and fourth nodes and identical seventh and eighth nodes is written as a C3D6 element.

Record key 1902 (below) defines the location of each active degree of freedom. For example, if the model contains only two-dimensional beam elements, the only active degrees of freedom are 1, 2, and 6. Therefore, this record would have the attributes (1, 2, 0, 0, 0, 3), meaning that degree of freedom 1 () is the first active variable at each node; degree of freedom 2 () is the second active variable at each node; degrees of freedom 3, 4, and 5 are not active in the model; and degree of freedom 6 is the third active variable at each node.

Any nodal or element data after this record refer to the eigenvector, until a new record key 1980 or a record key 2001 is encountered. Eigenvalue output for substructures (see “Writing the recovery matrix, reduced stiffness matrix, mass matrix, load case vectors, and gravity vectors to a file” in “Defining substructures,” Section 10.1.2) also uses these records to divide up elemental and nodal results. This record is written if there are any results file output requests for an eigenvalue buckling prediction or eigenfrequency extraction step. The generalized mass, etc. are not written for an eigenvalue buckling prediction step. This record is not written for a complex eigenfrequency extraction step.

The following record is written once per increment, after all data records have been written for that increment.
Record key: 2001 Record type: Increment end record
Attribute: 1 – No attributes.

Note: When binary format is used, the results file is written in blocks of 512 words for each increment. If there are fewer than 512 words in the last block of the current increment, record 2001 has zeros appended to it so that the total length of the block is 512. Hence, the length of record 2001 is 2 + the number of zeros appended. For an ASCII format results file record 2001 is extended to complete an 80 character logical record, and a logical record of 80 blank characters is added after this record. See “Accessing the results file information,” Section 5.1.3.
