Modelling a beam with a variable inertia
Modelling a beam with a variable inertia
(OP)
Hello,
I need your help about a modelling I'v got to do in order to find the vibration modes of a beam.
I hope you can understand what I mean, I'm french and I am not really fluent in english!
The beam has an "I" shape and a variable inertia (the height and the width change). However i can only make an extrusion with a constant sketch so I can't modell my variable inertia. Which function of abaqus should I use?
Thank you in advance for your help.

For example, this would be relatively easy in Patran (ground up) since you just create the points (4 for each cap and web, 12 total). Then create surfaces from those points. It would take just a few minutes.
Top down is great for solids and other things, but sometimes I like the ground up approach since it can be very flexible.
