Degrees of Freedom
Degrees of Freedom
(OP)
I recently read a paper mentioning that and FE analysis was conducted a mesh density of approx 10,000 degrees of freedom, can anyone explain this?
Thanks.
Thanks.

assuming a +ve outlook, the guy just grabbed a number (or was told to grab a number) to quantify the statement "the structure was modelled with a FEM".

RE: Degrees of Freedom
Finite Element Method involves breaking a structure down into elements with nodes, writing stiffness equations for each degree of freedom of each node, and then solving them simultaneously. 10,000 DsOF means that they solved a 10k×10k matrix. Be glad you did not have to do this by hand.

but i wouldn't bother checking it (if that's what you're intending on doing). it may be the same as the report, or the report could have rouned some. it'd be more relevent to check the results (compare the report data with the FE output). if you're really suspicious, rerun the model.

Numerical complexity is often a substitute for understanding.
