Syntax

integrator ICL (1) [2]
# (1) int, unique integrator tag
# [2] double, spectral radius, \rho_b, default: 0.5

Remarks

The following constraint applies.

$$0.5\leq\rho_b\leq1.0.$$

If the model is linear elastic, it is possible to indicate using

set linear_system true

to speed up the computation.
