Argument Descriptions

ParR

The name of the resulting numeric array parameter vector. See *SET for name restrictions.

Func

Fill function:

DATA

Assign specified values CON1, CON2, etc. to successive array elements. Up to 10 assignments may be made at a time. Any CON values after a blank CON value are ignored.

RAMP

Assign ramp function values: CON1+((n-1)*CON2), where n is the loop number (*VLEN). To specify a constant function (no ramp), set CON2 to zero.

RAND 

Assign random number values based on a uniform distribution RAND(CON1,CON2), where:

CON1 is the lower bound (defaults to 0.0)
CON2 is the upper bound (defaults to 1.0)
GDIS 

Assign random sample of Gaussian distributions GDIS(CON1,CON2) where:

CON1 is the mean (defaults to 0.0)
CON2 is the standard deviation (defaults to 1.0)
TRIA

Assigns random number values based on a triangular distribution TRIA(CON1,CON2,CON3) where:

CON1 is the lower bound (defaults to 0.0)
CON2 is the location of the peak value (CON1 ≤ CON2 ≤CON3; CON2 defaults to 0 if CON1 ≤ 0 ≤ CON3, CON1 if 0 ≤ CON1, or CON3 if CON3 ≤ 0)
CON3 is the upper bound (defaults to 1.0 + CON1 if CON1 ≥ 0 or 0.0 if CON1 ≤ 0)
BETA

Assigns random number values based on a beta distribution BETA(CON1,CON2,CON3,CON4) where:

CON1 is the lower bound (defaults to 0.0)
CON2 is the upper bound (defaults to 1.0 + CON1 if CON1 ≥ 0 or 0.0 if CON1 ≤ 0)
CON3 and CON4 are the alpha and beta parameters, respectively, of the beta function. Alpha and beta must both be positive; they default to 1.0.
GAMM

Assigns random number values based on a gamma distribution: GAMM(CON1,CON2,CON3) where:

CON1 is the lower bound (defaults to 0.0)
CON2 and CON3 are the alpha and beta parameters, respectively, of the gamma function. Alpha and beta must both be positive; they default to 1.0.
RIGID

Generates the rigid body modes with respect to the reference point coordinates (CON1, CON2, CON3). The dimensions of the array parameter ParR are (dim1,dim2) where dim1 is the maximum node number (including internal nodes but excluding orientation nodes) multiplied by the number of degrees of freedom, and dim2 is the number of rigid body modes (which corresponds to the number of structural degrees of freedom).

CLUSTER

Generates excitation frequencies with clustering option CLUSTER(CON1,CON2,CON3,CON4,%CON5%) where:

CON1 is the lower end of the frequency range in Hz (0 < CON1)
CON2 is the upper end of the frequency range in Hz (CON1 < CON2)
CON3 is the number of points on each side of the natural frequency (4 ≤ CON3 ≤ 20, defaults to 4)
CON4 is the constant damping ratio value or an array parameter (size NFR) specifying the damping ratios (if zero or blank, defaults to constant damping ratio of 0.005)
CON5 is an array parameter (size NFR) specifying the natural frequencies in Hz

The dimension of the resulting array parameter ParR is less than 2+NFR*(2*CON3+1) where NFR is the number of natural frequencies defined in CON5.

CON1, CON2, CON3, . . . , CON10

Constants used with above functions.

Notes

Operates on input data and produces one output array parameter vector according to:

ParR = f(CON1, CON2,  ...)

where the functions (f) are described above. Operations use successive array elements (*VLEN, *VMASK) with the default being all successive elements. For example, *VFILL,A,RAMP,1,10 assigns A(1) = 1.0, A(2) = 11.0, A(3) = 21.0, etc. *VFILL,B(5,1),DATA,1.5,3.0 assigns B(5,1) = 1.5 and B(6,1) = 3.0. Absolute values and scale factors may be applied to the result parameter (*VABS, *VFACT). Results may be cumulative (*VCUM). See the *VOPER command for details.

This command is valid in any processor.
