Hi Guys;

In finite elements, I would like to group the fragments areas, to assign a different material.
How could I select and group them?

Thanks for helping….

In H16 you can modify all the material properties of your tet mesh using multiplier point attributes.
As a rule, each of these multiplier point attributes has the name of the corresponding parameter in the Model tab of the solid object. For example, you can create multiplier point attributes:

stiffness
dampingratio
massdensity
shapestiffness
volumestiffness

Inside the solver, these attributes are multiplied with the settings in the Model tab.
So if you want to make a region half as stiff as the surrounding regions, you set the “stiffness” point attribute
to 0.5 in that region and to 1.0 everywhere else.

Thank you Michiel, very good tips.

I'm new to Houdini and I don't know how to use that attributes to assign several material to fractures parts
I would like to assign one material to body of my solid geometry, and another material to sliced parts…
Here in this attached image I show what I want to do :
