Hi,

Firstly, please see the previous discussion: https://innovationspace.ansys.com/forum/forums/topic/how-to-apply-remote-displacement-in-ansys-apdl-2/ 

Here, I try to first way succesfully but I try to insert remote displacement to ANSYS APDL/Mechanical by Code by Interface manually. For this, there is a second way "rbe and padt and ansys" google search but how to do by this way I didnot comprehend.

 

I tried to model simple 100x100x10 mm^3 (X,Y,Z) block in Workbench and see ds.dat file from Solution>Open Solver Directory. The model fixed at the bottom and remote displacement inserted along +z direction by magnitude of 3 mm.

Is there any process to extract code from ds.dat file? ds.dat file can be found in this link: https://stdyildizedu-my.sharepoint.com/:w:/g/personal/ahmet_yildirim4_std_yildiz_edu_tr/EaZ7B2tIZtVHiDhgbPyGTCwB5TE2EKrjlWR5k6RqqV_0sQ?e=mdzzNa

As special, I try to apply remote displacement in the time step of 2. Here is a some code I extract from ds.dat file (from another example block):

Is there any way to "Apply Remote Displacement in ANSYS APDL by Code or Interface"?

I am looking forward to any response.

 

Thanks a lot.

Hi,
There are a few similar discussion on forum, see if these help you out:
Remote displacement on Ansys Mechanical APDL
Remote Displacement using APDL (ansys.com)

Hi Harshvardhan,

I extract a code from discussions,

"""

nsel,s,loc,z,110

CM,P1,NODE
d,P1,uz,4

"""

But this is like a normal displacement just grouping them and then appl a disp. 

Trying to do:

For a wall, which has a thickness of 110 mm, I try to select all nodes at this z=110 mm and then apply remote displacement at the middle of the wall (LxH let's say).

How to rerrange the code, if you could see?

Thanks,

AY
