大神您好 我是在做岩土体开挖设置接触元的时候出现了这样的问题， 我在网上看到是说接触对设置太多可能会出现这样的情况，具体不清楚，地应力的计算都还可以 开挖之后就结果不好了 支护之后都不收敛了。下面是我具体出现的问题警告。请问需要怎么解决呢 *** WARNING *** CP = 206.375 TIME= 10:54:29 There are 74 small equation solver pivot terms. *** ERROR *** SUPPRESSED MESSAGE CP = 206.391 TIME= 10:54:29 The value of UX at node 126 is 2.681589959E+11. It is greater than the current limit of 1000000. This generally indicates rigid body motion as a result of an unconstrained model. Verify that your model is properly constrained. *** ERROR *** SUPPRESSED MESSAGE CP = 206.391 TIME= 10:54:29 *** MESSAGE CONTINUATION ---- DIAGNOSTIC INFORMATION *** If one or more parts of the model are held together only by contact verify that the contact surfaces are closed. You can check contact status in the SOLUTION module for the converged solutions using CNCHECK. *** ERROR *** SUPPRESSED MESSAGE CP = 206.406 TIME= 10:54:29 *** MESSAGE CONTINUATION ---- DIAGNOSTIC INFORMATION *** Rigid body motion can also occur when net section yielding has occurred resulting in large displacements for small increments of load or when buckling has occurred. You can plot the time history curve for node 126 in the UX direction to check for stiffness (slope of the curve) approaching zero. *** WARNING *** SUPPRESSED MESSAGE CP = 206.406 TIME= 10:54:29 The unconverged solution (identified as time 3.35 substep 999999) is output for analysis debug purposes. Results should not be used for any other purpose. |
