RANDT1

Bulk Data Entry Defines time lag constants for use in random analysis autocorrelation function computation.

Format


(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
RANDT1	`SID`	`N`	`T0`	`TMAX`


(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
RANDT1	5	10	3.2	9.6


Field	Contents	SI Unit Example
`SID`	Random analysis set identification number. (Integer > 0)
`N`	Number of time lag intervals. (Integer > 0)
`TO`	Starting time lag. (Real ≥ 0.0)
`TMAX`	Maximum time lag. (Real > TO)

At least one RANDPS entry must be present with the same set identification number.
The time lags defined on this entry are given by:
$T_{i} = T_{o} + \frac{T_{max} {- T}_{o}}{N} (i - 1), i = 1, N + 1$
Similar to RANDPS Bulk Data Entries, the RANDT1 Bulk Data Entries can be referenced either by:
- The RANDOM Subcase or Case Control Entry.
- A SET I/O Options Entry that is then referenced by a RANDOM Case Control Entry. 4
- A SET Bulk Data Entry with TYPE=MODE that is then referenced by a RANDOM Case Control Entry. 4
If a SET entry is used to reference multiple RANDPS data, then the RANDT1 entry with the smallest ID from set of referenced entries will be selected for the analysis.
For example:
```
RANDOM=2
SET 2 = 5,6,7
BEGIN BULK
$
RANDPS,5
RANDPS,6
RANDPS,7
$
RANDT1,5 → This RANDT1 entry is selected for analysis.
RANDT1,6
