thanks for the reply.
Iam trying to control it because I got an error like this
Element 2616 (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.
