For beams and pipes position 6 specifies which variation, if any, of the section type or test is defined in the file. The variation will depend on the type of test that is performed.
For simple load test s7 variations of the refinement of the mesh are modeled.
m Standard mesh
f Fine mesh
Simple load test sd tests all beam section types with any appropriate variations; for example, arbitrary and general sections can be used to model different cross-sectional shapes.
b Box section
c Circular section
d Default integration (see also r, s)
i I-section
l L-section
n Nondefault integration (see also 4, 5)
p Pipe section
r Thin rectangular section
s Solid square section, default integration
t T-section
v Section data defined using a table of values
1 Channel section, origin at shear center
2 Channel section, origin not at shear center
3 Slit circular section
4 Solid square section, nondefault integration
5 Thin rectangular, nondefault integration
6 Solid square section, nondefault local origin
Distributed load test d1 tests all section types and, for the *BEAM SECTION option, variations of the TEMPERATURE parameter.
g TEMPERATURE=GRADIENTS
b Arbitrary box section
l Arbitrary L-section
v TEMPERATURE=VALUES
1 Arbitrary box section, TEMPERATURE=VALUES
2 Arbitrary L-section, TEMPERATURE=VALUES
For all other tests, or if no additional information is required for the tests mentioned in this paragraph, an x is used in the sixth position.
For continuum, membrane, and truss elements the sixth character indicates whether the element uses full or reduced integration and, where applicable, any other variations such as hybrid, incompatible modes, etc.
c Convection
d Dispersion control
f Full integration
h Hybrid
i Incompatible modes
j Incompatible modes, hybrid
k Modified triangles and tets
l Modified triangles and tets, hybrid
r Reduced integration
y Reduced integration, hybrid
For gasket elements the sixth character indicates the type of model behavior used in the thickness direction of the elements.
c Elastic-plastic with creep
d Elastic with damage
h Elastic-plastic (high initial stiffness)
l Elastic-plastic (low initial stiffness)
For interface elements the sixth character indicates the general interface element category.
r IRSxA
s ISLxA
t ITT
g GAP
c Coupling (ASI)
For the contact pair approach the sixth character indicates the type of relative sliding.
f Finite sliding with the seventh character s
i Small sliding with the seventh character s
p Finite sliding between coupled temperature-displacement elements with the seventh character s
s Small sliding with the seventh character i or n; finite sliding with the seventh character s
For shells the sixth character indicates any noteworthy shell features (composite, general section, etc.) or variations of the mesh.
c *SHELL SECTION, COMPOSITE
2 *SHELL SECTION, COMPOSITE and *SHELL GENERAL SECTION
h *SHELL GENERAL SECTION, MATERIAL
l *SHELL GENERAL SECTION, COMPOSITE
f Fine mesh
m Coarse mesh
x No variation
For hydrostatic fluid elements and fluid link elements, the sixth character represents any variations in the input files.
f TYPE=FUNCTION (fluid link)
t TYPE=TABULAR (fluid link)
x No variation
For rigid elements the sixth character is x.
