CAA_ELEMENT_OUTPUT
Specifies a set of elements for CAA integrated-element output.
Type
AcuSolve Command
Syntax
CAA_ELEMENT_OUTPUT("name") {parameters...}
Qualifier
User-given name.
Parameters
- caa_output (string) [no default]
- Qualifier of the CAA_OUTPUT command that outputs quantities integrated over the elements defined here and defines the nodes referenced by the element connectivity.
- shape (enumerated) [no default]
- Topology of the elements in this set.
- four_node_tet or tet4
- Four-node tetrahedron.
- five_node_pyramid or pyramid5
- Five-node pyramid.
- six_node_wedge or wedge6
- Six-node wedge (prism).
- eight_node_brick or hex8
- Eight-node brick (hexahedron).
- elements (array) [no default]
- List of element connectivity.
- quadrature (enumerated) [=full]
- Quadrature rule used for volume integration.
- full
- Full quadrature.
- reduced
- Reduced quadrature.
Description
CAA_ELEMENT_OUTPUT( "sample elements" ) {
caa_output = "sample points"
shape = eight_node_brick
elements = { 1, 1, 2, 4, 3, 11, 12, 14, 13 ;
2, 3, 4, 6, 5, 13, 14, 16, 15 ; }
quadrature = full
}
defines two elements that will contribute to any element-integrated quantities specified in the CAA_OUTPUT command qualified by "sample_points". If there are no such quantities in the referenced command, then this command has no effect. The elements parameter defines the element connectivity and has the same format as the corresponding parameter in ELEMENT_SET (see that command for format and node ordering), but the elements defined here need not have any relationship to any other elements or element sets. The nodes contained in the element connectivity must all be defined in the referenced CAA_OUTPUT command. Unlike ELEMENT_SET this command does not support higher-order elements (that is, ten-node tetrahedra) or nodal quadrature.

CAA_ELEMENT_OUTPUT( "sample elements" ) {
caa_output = "sample points"
shape = eight_node_brick
elements = Read( "sample.elm" )
quadrature = full
}
A separate CAA_ELEMENT_OUTPUT command must be issued for each element shape and each CAA_OUTPUT command that references element integrated quantities.
