How to calculate surface moment of inertia of a generic section in Abaqus

[Cor46]

Hi,
For a structural study I'm trying to find a way on Abaqus to calculate the surface moment of inertia of a generic section (unit of measurement mm^4).
It's rather easy to extrapolate the mass moment of inertia (unit kg.m^2) insering the material density but I need the surface one to implement the Navier equation.
Thanks.

You can use *BEAM SECTION GENERATE to calculate section properties for an arbitrary section drawn as a 2D part and meshed with WARP elements. Check the documentation chapter "Meshed Beam Cross-Sections".
