我计算的是动态断裂这一块的内容,增加冲击速度,即载荷大小后,就出现下面的问题,请高手指点!
One or more elements have become highly distorted. Excessive distortion of elements is usually a symptom indicating the need for corrective action elsewhere. Try ramping the load up instead of step applying the load (KBC,1). 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. If this message appears in the first iteration of first substep,be sure to run shape cheching of elements.
