| Units |
Sets the unit of frequency. The choices are cycles/sec (Hz) and radians/sec.
|
| Lower limit |
Sets the lower limit of the exciting frequency to be considered in the solution (default is 1.0E-11). |
| Upper limit |
Sets the upper limit of the exciting frequency to be considered in the solution (default is 1.0E+5).
|
| Number of frequency points |
Sets the number of the solution's frequency points to be
selected between any two adjacent natural frequencies. The limit on
the total number of solution steps is 10000. |
| Correlation |
Sets the correlation between loads (including base excitation). If the excitations are correlated, the cross-spectral density terms are included in the analysis.
|
Fully correlated.
|
All loads are fully correlated.
|
|
Fully uncorrelated.
|
All loads are fully uncorrelated.
|
|
Partially correlated.
|
The degree of correlation is based on the relation between the spatial distance Rij of nodes i and j and the user defined RMIN (Inside radius) and RMAX (Outside radius).
- Units. Sets the units for the radius.
- Inside radius. Sets the inner radius (RMIN) which determines the degree of correlation.
- Outside radius. Sets the outer radius (RMAX) which determines the degree of correlation.
Partial correlation is used for force and pressure excitations.
