迈达斯civil--桥梁施工阶段划分好了运行分析出现问题，MIDAS JOB TERMINATED. REFER TO .OUT FILE

提示在下面，我的是悬臂浇筑的混凝土连续梁桥。提示55和18号节点奇异，我的是三跨的桥，55和18号节点是两边的1号块开始的地方，这两个节点上本来就没有什么约束条件，约束条件是加在0号块，搞不懂诶。有前辈可以解答一下吗，谢谢谢谢~WARNING : NODE NO. 55 RZ DOF MAY BE SINGULAR.WARNING : EQUATION NO. 330WARNING : NODE NO. 55 RX DOF MAY BE SINGULAR.WARNING : EQUATION NO. 328WARNING : NODE NO. 55 DZ DOF MAY BE SINGULAR.WARNING : EQUATION NO. 327WARNING : NODE NO. 55 DY DOF MAY BE SINGULAR.WARNING : EQUATION NO. 326WARNING : NODE NO. 18 RZ DOF MAY BE SINGULAR.WARNING : EQUATION NO. 108WARNING : NODE NO. 18 DY DOF MAY BE SINGULAR.WARNING : EQUATION NO. 104WARNING : NODE NO. 18 DZ DOF MAY BE SINGULAR.WARNING : EQUATION NO. 105WARNING : NODE NO. 18 RX DOF MAY BE SINGULAR.WARNING : EQUATION NO. 106WARNING : NODE NO. 18 RY DOF MAY BE SINGULAR.WARNING : EQUATION NO. 107ERROR NORM IS NaN or INFINITETHE PROGRAM IS ABORTED-------------------------------------------------------------ERRORS ENCOUNTERED.

Answer 1

感觉应该是施工阶段过程中边界组没加上或施加的边界组存在问题。

Answer 2

这个我也出现了，后面我改了边界条件，把支座的RX,RY,RZ全部勾选，你可以试着改一下支承条件。

Answer 3

midas官论坛问哪比较专业些
