hypermesh与abaqus联合仿真模型导入问题

何玄

在hypermesh中导出的拱坝inp模型导入abaqus中在最后的计算中总会遇到问题，我在hypermesh中检查网格的连接、warpage、skew、jacobian三项均没问题，但在abaqus中就有问题：Error in job Job-1: Too many attempts made for this increment
Job Job-1: Abaqus/Standard aborted due to errors.
Error in job Job-1: Abaqus/Standard Analysis exited with an error - Please see the  message file for possible error messages if the file exists.
Job Job-1 aborted due to errors.向高手请教一下你是怎么处理啊？

message file中后面显示：

这是计算不收敛的错误提示

请查看你的dat和msg等文件，查找具体原因。如果没有刚体位移，零主元等问题的话，那就是你的模型有问题
