Field |
Contents |
SID |
RCROSS set identification number. No default (Integer > 0) |
RTYPE# |
Type of response quantity. At least one field must be selected. If either RTYPE1 or RTYPE2 is blank, then the blank field takes the default from the defined field. DISP - Displacement vector |
ID# |
Element, grid, or scalar point identification number. No default (Integer > 0) |
COMP# |
Component code (item) identification number. See comment 2. No default (Integer > 0) |
1. | This entry is required for computing the cross-power spectral density function. SID must be selected with the I/O Option RCROSS. Fields RTYPE1, ID1, and COMP1 represent the first response quantity and fields RTYPE2, ID2, and COMP2 represent the second response quantity. |
2. | For elements, COMP# represents a component of the element stress or strain as described in the following table. |
