How to deform an existing mesh from CT measurements?

Hi all,

I would like to know if someone has a trick to deform a mesh generated in Abaqus thanks to Computer Tomography measurements ? 

The file I received from CT is a .stl.

Do you know an open source software that can compute deviations between point clouds?

Thanks in advance for your support :-D

If you can first align the FE model with the CT image, then you could interpolate the displacements at each node. From there you can apply the deformation.
