Hi Eugen,

randomDensePack calls TriaxialTest internally [1], which
calls TriaxialCompressionEngine internally [2], which is deprecated. So, as
the warning says, it should be replaced by TriaxialStressController. I have
no time to do it now, but this information may be useful for other people
willing to fix it.
cheers

PS: thanks for attached minimal working example, things are much easier
then :-)
