如下错误：
  
***ERROR: SURFACE ASSEMBLY_S3EWP2-3-U IS NOT CONTINUOUS. USE AVAILABLE POST PROCESSOR TO VISUALIZE THIS SURFACE.
  
怎么看SURFACE S3EWP2-3-U都是连续的。
  
怀疑第304行有问题
  
*CONTACT PAIR, INTERACTION=WP-CH, SMALL SLIDING
S1ECH1-2-3-D, S3EWP2-3-U
  
如交换主从面 ->  
  
*CONTACT PAIR, INTERACTION=WP-CH, SMALL SLIDING
S3EWP2-3-U， S1ECH1-2-3-D
  
则报S1ECH1-2-3-D不连续， 但不知问题出在哪？
  
还请大侠指教， 谢谢！

文件不全的说?

johnyan

我还在写History数据， 错误出在Model部分
现修改了文件，暂时去掉History部分
请 cafe0519 大侠帮忙看一下， 错在哪？谢谢！

对你这个问题本身不是很熟悉，但感觉可能是面S1ECH1-2-3-D的定义出了问题，因为该面是通过单元定义的，显然，用直线（四边形单元的边）去近似逼近一光滑的曲面S1ECH1-2-3-D自然会是不连续的，关于这一点，你将该局部放大即可清楚的看出：

But how to explain  
***ERROR: SURFACE ASSEMBLY_S3EWP2-3-U IS NOT CONTINUOUS. USE AVAILABLE POST PROCESSOR TO VISUALIZE THIS SURFACE. ?
  
S3EWP2-3-U is flat surface.
  
Also S1ECH1-2-3-D是连续的, 其一阶导数才是不连续的。

我也遇到了同样的问题，明明是一条线，可就是出现说表面不连续，不知如何修改。

ABAQUS requires the master surface to be continuous. That's why the error message is also exchanged for the two surfaces when you exchanged the slave/master surfaces. In other words, it only checks discontinuity of the master surface.
  
I cannot visulize the model by opening the .odb file generated with your .inp file. I would suggest you to simplfy the model and try to isolate the problem. This will also makes other people easier to analyze your problem.
  
Good luck.
