Dear,

I have simulated an assembly under a torsion moment. I would like to get how much an specific location of a part has turned but I am not sure how to do it.

this is the assembly

I have placed a cylindrical coordinate system on the face I want to evaluate:

And I would like to get results on these particular edges. Highlighted in blue:

Thank you very much in advance.

 

Best regards.

    Hello Julio,

    I will start by saying that this is a corrupted database you shared. The reason for this is most probably the names and special characters you use. Please avoid them in future simulations with SimLab.

    To solve this, you can export the geometry in *.gda (Mesh) and recreate the solution you want from scratch (Re import it in a new database).

    After this, you will need to do three things to acquire the rotation of a node. Let's say that you want to apply moment in the center of your RBE Node.

    1) Apply the moment at the center of the RBE.
    2) Enable the rotation results (Results > Rotation)

    3) Create a Local Coordinate System, update the solution and query the results to acquire the value. Remember, the only node with rotation is the one you applied the moment to. Here you only have one RBE.

    If you need to find the rotation in another point you will need to create another RBE body so that the value can become available. RBE3 would be the best way to go since it does not add extra rigidity to your model.

    I hope this helps.
