vfun

Mapdl.vfun(parr='', func='', par1='', con1='', con2='', con3='', **kwargs)

Performs a function on a single array parameter.

APDL Command: *VFUN

Parameters

parr

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

func

Function to be performed:

Arccosine: ACOS(Par1). - Arcsine: ASIN(Par1).

Par1 is sorted in ascending order. *VCOL, *VMASK, *VCUM, and *VLEN,,NINC do not apply. *VLEN,NROW does apply.

Compress: Selectively compresses data set. “True” (*VMASK) values of Par1 (or row positions to be considered according to the NINC value on the *VLEN command) are written in compressed form to ParR, starting at the specified position. - Copy: Par1 copied to ParR.

Cosine: COS(Par1). - Hyperbolic cosine: COSH(Par1).

Direction cosines of the principal stresses (nX9). Par1 contains the nX6 component stresses for the n locations of the calculations. - Par1 is sorted in descending order. *VCOL, *VMASK, *VCUM, and *VLEN,,NINC do not apply. *VLEN,NROW does apply.

Euler angles of the principal stresses (nX3). Par1 contains the nX6 component stresses for the n locations of the calculations. - Exponential: EXP(Par1).

Expand: Reverse of the COMP function. All elements of Par1 (starting at the position specified) are written in expanded form to corresponding “true” (*VMASK) positions (or row positions to be considered according to the NINC value on the *VLEN command) of ParR. - Natural logarithm: LOG(Par1).

Common logarithm: LOG10(Par1). - Nearest integer: 2.783 becomes 3.0, -1.75 becomes -2.0.

Logical complement: values 0.0 (false) become 1.0 (true). Values > 0.0 (true) become 0.0 (false). - Principal stresses (nX5). Par1 contains the nX6 component stresses for the n locations of the calculations.

Power function: Par1**CON1. Exponentiation of any negative number in the vector Par1 to a non-integer power is performed by exponentiating the positive number and prepending the minus sign. For example, -4**2.3 is -(4**2.3).

Hyperbolic sine: SINH(Par1). - Square root: SQRT(Par1).

Tangent: TAN(Par1). - Hyperbolic tangent: TANH(Par1).

par1

Array parameter vector in the operation.

con1, con2, con3

Constants (used only with the PWR, NORM, LOCAL, and GLOBAL functions).

Notes

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

ParR = f(Par1)
