Assuming you are running static linear analysis, here would be my approach:
FIRST:
Hand calculate a global freebody or use an FEM "stickmodel" to completely define your input loads and system constraints. Export both the reactions and loads as INPUT loads to your actual FEM.
SECOND:
Define a...
Hey man,
Just grab your surface & solid geometry and "Non-Manifold Add." This associates the surface and solid together.
Then, set your meshing attributes for the cube and surface, let'er rip. Might need to merge nodes along surf/solid intersection.
Don't even mess with the contact parameters...
Hi,
The comments are leaning towards the ever-important mantra emphasizing FEA as a tool. I wholeheartedly agree. Just so you have something to work off of: Validity tests like these are common - (NASA, Sikorsky, Lockheed) as they provide some level of assertion purporting the validity of...
gtae2002,
Thanks to your assistance I whipped up a handy copy/paster for freebody data structures using Excel VBA.
keep it simple:
PULL button copies freebodies from active model
then switch tabs in femap to another model
PUSH button pastes freebodies wherever you want it
I am a lazy coder...
Hello Eng-Tips,
I am writing a quick piece of code to store all of the freebody object properties in an active model session.
I am having difficulty using the GetElements method to retrieve all elements stored in the freebody entity. Documentation and examples for freebody objects in the API...
