MATLAB: Interpolation strain tensor field

interpolationtensor field

I have a 3D+t strain tensor field (3D over time) delivered by FAM software (Abaqus). What I need is to interpolate the strain tensor on a fixed plane to gest a 2D tensor maps over time. Can I use the intrep3 function for that interpolating each component of a tensor? Is there any better solution for this problem. I have read that it is better to interpolate eigenvalues and eigenvectors but I did not found details about how to do this

You can interpolate the strain components easily with the interp3 function, and the method linear.
Is it an elastic material? If so you could reconstruct the strain tensor by interpolating only the displacement and using the shape functions...
Which kind of elements are you using?
