materials, density, visualization... 1

[skanskan]

Hi.

What's the relationship between the material assigned to a body from
"tools -> materials -> assign materials"
and the materials assigned during the simulation
and the system materials (visualization).
and the "edit -> feature -> solid density"

Can Anyone rule any the other?

OK, the first two...

"...the material assigned to a body from "tools -> materials -> assign materials"
and the materials assigned during the simulation..."

...are one and the same. If you assign a material using "tools -> Materials" and you were to later enter Simulation, it will show you that the material has already been assigned. Now you can override it there if you wish, but if it's already what you want, you don't have to do anything else.

The third item, materials assigned when rendering a model, these are for 'visualization' purposes ONLY. It will have no effect whatsoever on the density or what the simulation package is using.

As for the fourth item, 'Solid Density', this was a precursor to the ability to assign an actual material using the first/second item above, and it ONLY does that, assign a density to a solid used when computing Mass Properties. Note that if you assign a 'Solid Density' and then assign a Material, the Material assignment will overwrite the first density assignment.

I hope that's clear as to what these are used for and their relationships to each other, when there is any.

And how do you see all the materials already assigned?

Every body that has had any actual Tools -> Materials assigned to it will also have an Attribute assigned to it which gives the Material name. There will also be a matching Part Attribute assigned the part file. Edit the material by doing another assignment will update these attributes so you can use Properties -> Attributes to learn this form individual bodies or the current part file.

Also, if you do an Info -> Object and select the Solid Bodies, you'll see included in the listing window report, the materials assigned to each of these selected bodies.

Also of note: on the "assign material" dialog box (Tool -> Materials -> Assign materials...) there is a button that will highlight all the bodies that have NO material assigned to them.
