# Is it possible to obtain the relative displacement contour of a single part without the translations/rotations of the whole model?(Abaqus)

Is it possible to obtain the relative displacement contour of a single part without the translations/rotations of the whole model?(Abaqus)

Hello,

You can define a node set (see

NSET1below) that includes only the nodes of the specific part from which you want the relative displacements, and then extract these displacements in Matlab. This can be done in the Abaqus input file as follows:Regarding the "relative" displacements, please explain in more detail what do you mean by "relative".

Best regards

Thank you very much for your reply, I did not explain it very well.

The displacements i'm trying to get are the displacements of the individual part without the addittion of the translations of the rest of the model, like in a whole model analysis see how much a small pin deformed.

I guess I'm looking to define a coordinate system fixed to a point in the middle of the part and for it to follow this point during the analysis?

There are two options to find the relative displacements:

1)Use the following options for defining a local coordinate system that is fixed to the center of the part and moves with it:2)Subtract the displacement of the center of the part from the displacements of all nodes defining the part. In this way you will get a displacement field with respect to the part center.I hope that the above help you. Let me know if you need further guidance regarding this.

Best regards.
