Numerical singularity in Abaqus

 

Hi All,

many a times in abaqus, we get numerical singularity warnings. which are mainly due to rigid body motion in one or more directions. This will generally happen when there is contact closing and opening phenomenon is happening.  How can we resolve these numerical singularities? Please post if you have any additional information.

 Thanks and Regards
