Debriefing: HW-2A & Working Plane

ELEMENT Type > Add/Edit/Delete > OPTIONS

Choose element behavior: ____________ stress,  ___________ strain, and axisymmetric.

Note:         s_Z = 0 for cases of plane _____________

                      s_Z ≠ 0 for cases of plane _____________  

ANSYS does NOT check your UNITS !

Your job: make sure dimensions, loads, and material data units are ____________

SmartSizing

• Computes estimated element edge lengths for all lines in the areas or volumes being meshed
• The edge lengths on these lines are then refined for curvature and for proximity of other features in the geometry.

Working Plane – construction plane

            Can also be an ________________ tool (divide areas or lines by WP)

            Why re-align with global Cartesian ?  _____________

            What is “global Cartesian” ?  ____________________

 ________________ Operation:
A new area is created which is equal to the common area of the original set of areas. New areas are created by trimming the original areas to make room for the new area. All areas share common lines and keypoints at their boundaries.

 DELETE > LINES > Pick, ALL – does NOT destroy your model.

            Which lines are NOT deleted ?

            Why were extra (unused) lines in your model ?

 Stress Hand calc – WHERE ?  (specific point and direction)
