Subroutine Type

Utility/Data Access

Definition

The SET_DAE_ERROR utility subroutine sets the integration error tolerance for the DAE integrator DSTIFF.

Calling Syntax

Fortran

CALL SET_DAE_ERROR(ERROR)

C

c_set_dae_error(error)

Python

py_set_dae_error(error)

Matlab

m_set_dae_error(error)

Input Arguments

ERROR

A double precision value that specifies the error tolerance to be set for the DSTIFF integrator.  ERROR must be greater than zero.

Output Values

NONE

Complete Definition

The SET_DAE_ERROR is a function style subroutine which can be used in a TUNSUB subroutine to set the integration error tolerance for the DAE integrator DSTIFF and for FIM_D.  Using this function, the integration error tolerance can be modified spontaneously as per the simulation needs.

This function is typically used to improve accuracy or performance of the multi-body simulation.

Example

Please see TUNSUB for a GETNUMID usage example for SET_DAE_ERROR.
