Rocky DEM FAQs

Rocky DEM particle simulation

Can you model cohesion or adhesion in Rocky?

Yes. Any particles modeled in Rocky can have different friction coefficients, or other material properties custom-defined within Rocky.

What types of particles can you model? Are there limitations to size/shape?

Rocky can model solids, shells, flexible fibers and more. Virtually any shape or size 3D volumetric shape which can be imported in an STL format can be used as particle for bulk modeling and particle interactions within Rocky.

Can you import or export Rocky DEM data into other FEA or CFD tools?

Yes. Rocky DEM is tightly integrated with ANSYS tools and can also provide 1-way coupling to other 3rd party FEA or CFD analysis systems.

Does Rocky DEM have its own standalone solver? Pre-processer? Post?

Yes. Rocky has its own proprietary solver technology and can also provide fully bundled or separate Pre and Post processing capabilities.

What about multi-core solving? Does Rocky scale?

Yes! Rocky provides solving on 2 CPU cores out of box but can enable scaling to a virtually unlimited count of CPU or GPU (recommended*) cores with associated licensing.

How many cores come out-of-box?

Rocky DEM provides solving on 2 CPU cores out of box. There are also CPU and GPU “packs” for multi-core processing. Because each model and hardware/software configuration is different, we recommend talking to our sales and technical personnel.

Are there workshops or sample files/models inside of Rocky?

Yes! There a number of sample files that help get you acclimated with the GUI and workflow.

How many particles can Rocky DEM solve for?

Unlimited! As much as you have time and hardware to support. The greatest limiting factor in terms of particle count is solve time, which varies with each model and hardware configuration.
