Hello All
I have created a fixed joint in Ansys Mechanical model and shared it with subsequent System next. Although the coordinate system of the geometry was not matching so i transformed the geometry using part transform in ANSYS mechanical. Now the reference coordinate system is at location predefined as it can be seen that the spider is located far from the scoped geometry. But does it affect the results?

Hi

Please refer to this KM I'm using joints in my model in Mechanical and the model does not converge with joint related errors? Also no motion is seen, joints seem locked? - Ansys Knowledge

Thanks

Joints are created with a reference coordinate system at global coordinates which creates the problem you observed when the parts are transformed.

If you only need the part to move once, manually update the coordinates of the joint reference coordinate system.

If you need to part to move often, create a new coordinate system that is scoped to a feature on the geometry such as a circular edge or cylindrical face. Then update the joint reference coordinate system to use the newly created joint AND update the values of the coordinates to 0,0,0 becuase they will be set to values that leave it were it was.  Now when the part is moved, the reference coordinate system will move with the geometry.
