…Workshop 1A: Auto Contact Detection
Note the numerous regions, color coded as orange (Bonded in a Closed status, but with penetration or gap same order of magnitude as pinball). These may or may not be acceptable, but they need to be reviewed carefully.
Expand each folder in the project tree to become familiar with model entities.
Note especially the multiple contact pairs, joints, circular beam and longitudinal spring element.
…Workshop 1A: Auto Contact Detection
Highlight the Engineering Data Cell and double click to open • Verify the predefined material properties • Verify that the units are in Metric (kg,mm,…) system. • If not, fix this by clicking on…
