LINK 180 ELEMENT PROBLEM

[3JC]

Dear friends of the ANSYS forum,

I am new on the use of ANSYS, and for instance I am performing basic tutorials such as the next:

https://www.youtube.com/watch?v=T9V6lZSyjcs

But I have a problem from starting :- I have tried to do the next tutorial, but when I try to define the section property of the LINK 180 element (

https://www.sharcnet.ca/Software/Ansys/17.0/en-us/help/ans_elem/Hlp_E_LINK180.html

), defining it as a real constant, I have the next error:

"Real constants for the element type are no longer supported"

I have been looking for information in internet, but I couldn't find any procedure on the graphical interface, by clicking with the mouse as on the tutorial (only typing the next code):

secdata, 0.5

Could you please tell me what I can I do.

Thank you very much for your attention. Regards,

3JC

V13 was the last version that used real constants for section properties for LINK180. Starting at V14, section data is input with the SECTYPE and SECDATA commands.
