Optional parameters

NAME

Set this parameter equal to the name of the output SIM document to which the reduced basis data are written. See Input Syntax Rules for the syntax of such names.

The default name is jobname_RBn, where n is the current step number of the job.

Data line to define the level of reduction

First (and only) line

  1. Level of reduction of the nonlinear deformation space given by a dimensionless value between 0 (the number of basis vectors and the number of nonlinear deformation fields from preceding operator output requests are the same) and 1 (no basis vectors are kept). The default is 10−4.

  2. Level of reduction of the auxiliary linear deformation space given by a dimensionless value between 0 (the number of residual basis vectors and the number of natural frequency modes from preceding analysis steps are the same) and 1 (no residual basis vectors are kept). If no value is specified, the same level of reduction is used as for the nonlinear deformation space.
