I used the sandstone material from the WB base with More-Columbus. But it also doesn't wobble.

I found my mistake: the snippet-material needs to be inserted into the geometry part.

But why doesn't the stuff work in LS-Dyna prepost (not WB)?

And in the Workbench, an error will appear on "_TITLE" in the title of the material.

After failing the sandstone and concrete materials from the WB base with More-Columbus, I decided to try the Johnson-Holmquist material.
