Contents |
SCID |
Section identification number. No default (Integer > 0) |
G0, G1, G2 |
Grid points defining the local axes of the section. G0 and G1 define the local x-axis while G0, G1, and G3 define the local xy-plane. No default (Integer > 0) |
GRSET |
Grid set identification number. No default (Integer > 0) |
ELSET |
Element set ID. Only sets of SOLID, SHELL, ROD, BAR, and BEAM elements can be used. (Integer > 0) |
IFRAME |
Flag for computing the center of the output coordinate system. The local system is defined by G0, G1, and G2. Default = 0 (Integer = 0, 1, 2, 3, 10, 11, 12, or 13) 0 – Origin of the local system defined by G0, G1, and G2 1 – Geometrical center of the section grid in the local system defined by G0, G1, and G2 2 – Center of gravity of the section in the local system defined by G0, G1, and G2 3 – Origin of the basic system in the local system defined by G0, G1, and G2 10 – Origin of the basic system 11 – Geometrical center of the section in the basic system 12 – Center of gravity of the section in the basic system 13 – Origin of the basic system |
CID |
Moving coordinate system identifier for automatic definition of a section. Only CORD1R and CORD3R can be selected. See comment 4. Default = 0 (Integer > 0) |
DT |
Time step for saving the data. Default = DTTH defined on XSOM (Real > 0) |
| 1. | SECT output must be selected for time history output with XHIST. It is only available for geometric nonlinear analysis subcases which are defined by an ANALYSIS = EXPDYN subcase entry. |
| 2. | Moments are computed with respect to the section center defined by the parameter IFRAME and expressed in the local section frame. |
| 3. | Normal force is the component normal to the XY plane of the section. The tangential force is the component in the plane of the section. |
| 4. | For CID > 0: |
| • | G0, G1, G2 blank – the local system of the section is built from the grid points defining the CORD1R or CORD3R. |
| • | The element set is created automatically from the elements intersected by the xy-plane of CID. |
| • | The grid set is created automatically from the grid points of the intersected elements on the positive z-axis defined by the xy-plane plane of the frame. |
| 5. | This card is represented as an interface in HyperMesh. |
