MONCARL

I/O Options and Subcase Information Entry Used in the Subcase Information section to identify the Monte-Carlo simulation control settings for non-parametric method for variation modeling.

Format

MONCARL(NSAMPLE=N,SEED=S,OFFD=OD,NGRP=NG,ZERO=EPS) = option

Definition

Argument Option Description
N <n>

Integer > 0 (Default = 0)
n
Number of Random Samples.
S <s>

Integer > 0 (Default = 777)
s
Random Number Generated Seed.
OD <od>

Real (Default = 1.0)
od
Scale factor for off-diagonal entries of the random matrix.
NG <ng>

Integer > 0 (No default)
ng
Number of DDM groups for the parallel processing of samples.
EPS <eps>

Real > 0.0 (No default)
eps
Threshold for identification of 0.0 eigenvalues.
option < SID >

No default
SID
Set identification of an MONCARL Bulk Data Entry.

Comments

  1. MONCARL Bulk Data Entries will not be used unless selected in the Subcase Information section.
  2. MONCARL is only supported for Modal Frequency Response analysis and only a single subcase of Modal Frequency Response subcase can be defined.
  3. Multi-level DDM is not supported along with MONCARL, regardless of whether or not the NGRP option is used on MONCARL.
