How can i define a torsional spring-damper element in ANSYS Workbench?

      Dear all, i'am trying to model a curved beam supported by torsional spring-damper elements and longitudinal spring-damper elements in ANSYS Workbench. I want to do an harmonic analysis on it but i need to verify if the torsional spring-damper element is defined correctly.

      In the ANSYS Forum, i've found that i can't define a Torsional Spring-element in workbench, but i can convert a Longitudinal Spring-damper to torsional by inserting a Command Object under the spring-damper and forcing it to be Torsional. I added longitudinal spring and added command right below it but i need to verify if the command is defined correctly.

      The torsional spring is arounf the X axis and the added command looks like the following:

      et,_sid,combin14

      KEYOPT,_sid,2,4

      K=158400

      CV1=150

      r,_sid,K,CV1

      Does any body have any idea on it?

      Thank you so much for the help.

      Hi

      This post shows how to use the torsion spring inside Mechanical (no need for apdl commands):

      All the best

      Thank you so much sir for your answer, but i don't know if beta restrain the rotation about the x axis or about all axis because in my case i need only to restrain the rotation about the x axis
