155 Default Pinball Radius Factor for Shells • When we define a contact, the APDL calculates a default pinball radius • Circle for 2D or a sphere for 3D of radius 2*depth (rigid-flex contact) or 1*depth (flex- flex contact) of the underlying element. • In Mechanical, the default pinball radius factor when using Program Controlled option is always set to ‐ 0.0 for most contacts -> solver will decide the factor. ‐ 1.0 for shells (spurious contact and slow contact searching). Too Large!! ‐ Solver recommends 1.75 to 0.5 (rigid – flex), 0.5 to 0.25 (flex- flex) for bonded and no separation contacts • Solution: Issue 0.0 and let solver decide the pinball radius factor
