Hi everyone,

I want to simulate particles transport in Rocky DEM 2022R2. I read that now it works with a one-way transient simulation for coupling with Ansys Fluent (Only data is tranferred from Fluent to Tocky during the transient simulation of the case in Fluent). I could not find any tutorial for this, and I did not see any option directly in Rocky DEM to activate this option. There is a new tab in Ansys Fluent though as in attached picture, but still dont know which option to choose. Any lead? 

Thank you so much.

Hello, 
 

As a starting point, I would suggest you to check this webinar on CFD-RockyDEM coupling: Particulate Modeling with RockyDEM | Ansys Webinar

 
Thank you,
Nikhil

Hi Nikhil,

Thank you for your reply.

I have seen related webinars and have simulated some of my cases. The previous versions were solving with a tow-way coupling approach or steady fluid flow, but it looks new version of 2022R2 works with a one-way transient flow too. I am not able to set up the model with this new one-way transient case.

The setting is on the Rocky side. Once you have the files from Fluent, link via the CFD Coupling > One way > Fluent-Particle option in Rocky.

Actually once you have your Fluent data (and case file) the work is only to be done in Ansys Rocky as Prof. Rob mentioned.

Hi Rob,

Hi DrAmine,

Thank you for your help. 

I also found more explanation in the Rocky manual for one-way transient analysis (Section 3.3.11.3 of help manual)

 

Thank you.
