When using cifs to mount a shared folder before, I did not pay close attention to the version of the SMB protocol¹. The following command line does not specify the protocol version:

When Ansa is used as Abaqus preprocessor for analysis, the problem of applying bolt pretension is often encountered. In addition to the complex settings, it is also easy to make mistakes, and various problems may occur if you are not careful. The following records the Ansa bolt pretension setting process and some easy mistakes, which will be used as a reference for related analysis later.
