1D and 3D solution

[Jessika]

hi
i am using abaqus to simulate spherical indentation. i am modeling viscoelastic material.
The aim from this study is to determine the rheological parameters of the material.
So can any one know what is the relation between parameters of the 3D model and the 1D model
that is thee difference between the numerical solution(FEM) and the analytical solution.
Thanks.

any suggeston please.
I mean whith my question, what is the difference between analytical solution and numerical solution

Not sure what you mean by parameters

thanks for your response
i mean by parameters the 3 parameters of rheological for example if we talk about a Zener model then we have 3 parameteres E0,E1 and mu.
