Hello all,

 

I am doing currently Harmonic Simulation  In Ansys Workbench. I want to apply moment on the surface which is already listed in the Named Seelction. I want to apply Moment using APDL code in Commands. I am applyng the moment using APDL code M but it seems its not working at all. The Surface Name is FACE and i am using following APDL code in commands.

 

cmsel,s,Face,Node

f,all,mx,%Moment_r_x%,%Moment_r_xi%

 

f,all,mz,%Moment_r_y%,%Moment_r_yi%

 

if anyone can help with this problem it would be a big help to me.

 

Thank you in advance!

In general the above should work (assuming the tables are OK). Since We do not have a screenshot or description of the model, we make a guess.

The most likely cause is that you are using this command on 3D elements (e.g., HEX or TET) that have only UX, UY, and UZ dof and thus accept only forces, FX,FY, and FZ (so no moments - hence the mx label is not applicable for these elements - it is to be used with shells and beams only that have rotational dof).

Hi Ekostson,

Thank you fro your reply. Is there any other way to convert this 3D elements in 2D elements (shell) in workbench using apdl commands and then apply moment on this 2D elements?.

thank you.
