Hello The the following APDL code is for converting cylindrical joint to Screw joint , can any one explain this code in detail?
keyo,_jid,1,17
sectype,_jid,joint,screw,_wbjoint
pi=acos(-1)
secjoin,,12
pas=1
secjoin,pitch,(pas/2/pi)

i was able understand the syntax of SECTYPE, SECJOINT, but what is SECJOIN ? whether SECJOIN is correct?

The command defines the keyoption, section type, and the other parameters like secjoin (defines local coordinate systems at joint element nodes and other data for joint elements) for the joint under which the command is specified. If you open up the solver files directory then in the same folder you can look up the ds.dat file which acts an input file for the Workbench. For commands used please explore the Ansys Help.

Hi Ashish Thank you for your reply, Can you explain the following line secjoin,,12
Here value 12 signified the effective length of the bolt or the outer radius , what does the value 12 signify?

[Ashish Khemka]

This command defines local coordinate systems at joint element nodes and other data for joint elements. Please refer to the following link for more details:

SECJOINT (ansys.com)

Value of 2 indicates Local Coordinate System 12 for the joint node.
