Buckling Verification with Autodesk Nastran In-CAD

o In this webinar Dean Rose and Marwan Azzam explore the intriguing world of buckling simulations within Nastran In-CAD 2016. An overview of available analysis types is given including linear buckling, non-linear buckling, linear static stress, and non-linear static stress analysis. The workflow and how each of these fit into the engineers toolbox is demonstrated. Specific details about buckling are provided in great depth and then reinforced with a live demonstration.

Dear friends,
If I want to model a taper column with circular cross section in Autodesk Nastran in-cad software and consider its buckling under self-weight, top point load and finally in existence of lateral load (static and dynamic). the problem at this point is that my column's modulus of elasticity varies linearly from bottom to the top of column.
is it possible to model this column and define a function for E(elastic modulus) in Autodesk Nastran in-cad? if so, how can I do that? I will greatly appreciate you if you can let me know how to model my column.
Thanks for your time,
Warm regards,
Mojtaba

Best way to test it is to test it ... in reality. Otherwise, awesome.
