Hello,

I want to export stresses from mesh in Mechanical and map these onto a set of DEM particles in Ansys Rocky. Any ideas?

Best regards

Dayana

Hi,

 

It is only possible to analyze the influences of particles in structures (1-way coupling, as done in Rocky tutorials 12 and 15) nowadays, and not from structures in particles. The 2-way coupling for FEA-DEM is a demand for Rocky and is on track for the future. 

 

Kind regards,

Lucas

Hi Lucas,

nontheless, it should be possible to modify certain particle properties e.g. velocity, forces... in Rocky by assesing their pointer such as a group of particle can get a cetrain force. This is for example possible in many DEM enviroments such as PFC, Lammps etc. Any idea to modify particle properties by Python shell or Solver C++?

Thanks a lot

Hello Dayana,

 

You can go to Rocky Menu | Help | Manuals | API:Solver Manual to check the available hooks for building a custom module in order to modify your simulation physics. 

If you don't know how to compile a custom module yet, check Rocky Tutorial 23.
