Learn the background to mass modeling.
- [Instructor] In this video we're going to take a look…at things which affect the mass distribution…within a dynamic analysis.…In other words, mass modeling.…Now mass modeling, we can think about element density,…so that's like a material density.…It's applied via the material property.…It's input in the Nastran In-CAD tree,…so we're going to find we pick up a material.…We're going to use typically carbon steel.…There'll be a density associated with that.…So here's the carbon steel,…and the value is a mass density.…
So we see the term highlighted in there.…Now it's input in the Inventor model tree.…If we go straight to the geometry,…the value there is a weight density.…And we can see there it's described as pound per cubic inch,…but it is a pound weight.…Now we need to consider mass versus weight,…particularly if we're working in the US.…In US units, the traditional units are pound, force,…inch, seconds, and that pound force is a weight,…and that's the fundamental quantity.…
Now, philosophically it's easier to understand…
