[求助]
求大神帮忙：ANSYS模拟钢筋混凝土板并考虑粘结滑移，无法求解（附命令流）
|

建模是利用分离式建模并在钢筋混凝土间施加弹簧单元，但在这一块理解不到位很可能出错了。 求解出现的警告和错误主要是说约束不足和出现大位移。 *** WARNING *** CP = 54.141 TIME= 17:41:19 There is at least 1 small equation solver pivot term (e.g., at the UZ degree of freedom of node 1) which may indicate a numerically unstable model. Please check your results carefully. *** WARNING *** CP = 61.250 TIME= 17:41:23 An extremely large pivot ratio has been detected by the sparse solver. This usually indicates a very ill-conditioned matrix or possibly rigid-body motion. The solution may be inaccurate or even erroneous. Please check your results carefully. *** ERROR *** CP = 61.391 TIME= 17:41:23 The value of UZ at node 238 is 1.695793158E+23. It is greater than the current limit of 1000000 (which can be reset on the NCNV command). This generally indicates rigid body motion as a result of an unconstrained model. Verify that your model is properly constrained. *** WARNING *** SUPPRESSED MESSAGE CP = 163.281 TIME= 17:42:23 The unconverged solution (identified as time 1 substep 999999) is output for analysis debug purposes. Results should not be used for any other purpose. |
