This may produce inaccurate results for bonded and no paration contacts using formulation other than MPC. This large penetration/ gap can be indentified by generating the initial contact results.船过水无痕 3. At least one body has been found to have only 1 element in at least 2 directions along with reduced integration. This situation can lead to invalid results. consider changing to full integration element control or meshing with more elements. 4. The uncoveraged solution(identified as substep 999999) is output for analysis debug purpos. Results at this time should not be ud for any other purpo. 5. one or more contact regions may not be in initial contact. check results carefully 6. contact status has experienced an abrupt change. check results carefully for possible contact peration 7. one or more bodies may be underconstrained and experiencing rigid body motion. weak springs have been added to attain a solution. 8. copying the source mesh to the target face failed becau of the poor quality. plea review your surface mesh, review the mesh, and t or adjust size controls to help the sweeper generate higher quality source and target surface meshes. after you are satisfied plea generate the volume mesh again. 香椿豆1，说你计算是由非线性问题导致不收敛 2，说你接触对有大的间隙问题，不晓得你用什么接触，但下面这四个地方值得你借鉴： 3，说你网格有问题，仔细划分一下网格吧，接触面上的网格大小要尽量一致，用size控制一下边啊，面啊、体啊啥的，最好用六面体网格（可用multizone方法）。 4，建议你用通过增加时间步来计算 5，说你有些地方没有设置接触，自动接触可能有漏，建议你检查一下 6，还是说你接触有问题 7，说你约束有问题，静态计算时，有物体移动。建议weak springs 设置成自动，检查一下约束，能保证物体在加载过程中没有大的移动 8，说你网格划分有问题 |
