Structural Joints

Model Reference Manual

Data Consistency Checking : Setting Geometric Error Limits : Structural Joints

The positional errors for Joints are measured as divergences of the Joint positions from their owning Nodes. The maximum permissible errors are defined, as for Sections, in terms of a Joint’s eccentricity.

Note:

Joint eccentricities are defined separately for Pjoint (Primary Joint) and Sjoint (Secondary Joint) elements.

Keywords:

ECCENTRICITY PJOINT SJOINT

Description:

The ECCENTRICITY PJOINT and ECCENTRICITY SJOINT commands specify the maximum permissible distance between the position of a Primary Joint or a Secondary Joint, respectively, and that of its owning Node before a diagnostic message is output.


Examples:
ECC PJOINT 1 (Default)	Maximum error in Primary Joint position is 1 mm
ECC SJOINT 1 (Default)	Maximum error in Secondary Joint position is 1 mm
ECC PJOIN 0.1 INCH	Maximum error in Primary Joint position is 0.1 inch
ECC PJOIN DEFAULT	Resets permissible Primary Joint error to 1 mm
ECC SJOIN DEF	Resets permissible Secondary Joint error to 1 mm
