F_Mean

Mean value of the normal distribution

(distribution of factors applied to shell thicknesses applied to selected parts)

(Real)

Deviation

Deviation of the normal distribution

(Real)

Min_cut

Minimum value

(Real)

Max_cut

Maximum value

(Real)

Seed

Seed of random noise

Default = 0 (Integer)

= 0: a random seed value is used

Idistrib

Distribution type

Default = 0 (Integer)

= 0: default, set to 2

= 1: Random distribution

= 2: normal law distribution

grpart_ID

(Integer, maximum 10 digits)
hmtoggle_plus1Comments
1.This option is multiplying generated real values (following the defined normal distribution) to shell thicknesses of selected group of part.
2.Curve of probability density function:

perturb_density

3.Seed is an Integer corresponding to the value used to initialize random number generation that should use for sensitivity analysis or model robustness investigation purpose.
4.Two computations with the same values, Seed will return exactly to the same results.
5.If random value is > Max_cut, random value is replaced with Max_cut.
6.If random value is < Min_cut, random value is replaced with Min_cut.
7.This option is compatible with property TYPE1.
