Soil material in optistruct

Alberto Buccellato

I wanted to simulate materials like loose sand or clay-like materials. What would be the best settings and properties to set?

It might depend on the kind of analysis, but you probably can take a look at Mohr-Coulomb and Drucker-Prager

how i can set up the mohr coulomb analysis through hypermesh? Usually i conduct a linear direct transient analysis with a mats1 card for the soil material.
