Thanks for the info, but this is for beginners.
Attached screenshots, maybe it will help:
Stage 1 ekill is successful, stage 2 elive successful, when the teeth are stretched, the movement begins and 80% of the grid error is resolved:
*** ERROR *** CP = 1909.812 TIME= 15:02:06
Element 3170 (type = 2, SOLID186) (and maybe other elements) has become
highly distorted. Excessive distortion of elements is usually a
symptom indicating the need for corrective action elsewhere. Try
incrementing the load more slowly (increase the number of substeps or
decrease the time step size). You may need to improve your mesh to
obtain elements with better aspect ratios. Also consider the behavior
of materials, contact pairs, and/or constraint equations. Please rule
out other root causes of this failure before attempting rezoning or
nonlinear adaptive solutions. If this message appears in the first
iteration of first substep, be sure to perform element shape checking.
I also tried making the grid more frequent:
But it doesn't help. I solved the problem in static structural. Maybe I should switch to transient?
