Finite elements have rules that govern what loads and constraints they can support. We call them degrees of freedom. In this webcast, we’ll shed some light on what degrees of freedom are and why they matter.

What will be the degree of freedoms to be restricted while dealing with the problem based on front roll over roll cage

Hi Great video! thankyou very much, I'm going to check all your channel. I have a question. How do you know that some nodes from the shell at the "right" side of the connection are doing contact with others nodes in the solid? ( min 19:48) It doesn't look like... Thanks!

Rob, I have a doubt regarding QUAD4 element that for a single QUAD4 element how many rigid body modes will be there?

i would suggest using animations to explain

So there's a really big caveat here when you say "Solids are the most common element" and that is when you work in the aerospace industry or any modeling situation where you have large assemblies then you will be avoiding solids like the plague itself. You'll use shells a lot especially in the aerospace industry. And when you try to combine solids with anything other than solids (as this video shows) you end up with a lot of work.

Same in a pressure vessel and piping industry. Stresses with Shell elements are more conservative and ASME loves that.
