I'm looking to access Ansys Rocky DEM to run a coupled simulation with Fluent.
Please let me know if there are tutorials and is there a student version for Rocky DEM.

The tutorials are currently all on the Ansys Learning Hub, which requires a subscription. I understand some material will be added to the AIS Learning system but don't have a date for that.
At present Ansys Rocky is not included in the Student bundle. To run a coupled calculation you'd need (I think) a Research level licence of both Fluent and Rocky. If you talk to University IT they may be able to check what is available on the Campus network and who on the Ansys side to discuss this with.

Thanks, do you think I can see deposition of particles on surfaces if I change the coeffecient of restitution for the reflect boundary type on Ansys Fluent DPM model?
Is there a way in which I can manually input the coeffecient of restitution and other quantities which help in particle sticking to a surface?

You will, but as DPM is a point mass you may find the number of "stuck" particles to become excessive which may cause solver issues. You also won't see any blockage effects.

Could you please explain what you meant by blockage effects?

DPM particles don't occupy volume, so the surface can have an infinite number of parcels on one cell facet. The particles can't then build up, so you won't get a pile of particles blocking the flow.
If you consider pouring sand onto a surface. In reality you'll get a pile. In Rocky you'll get a pile. With Fluent DPM you'll have a round patch on the surface.

So you mean to say there's no way to see accumulation in fluent? Even for inert particles in DPM (I guess inert particles have mass)
Is there a way to use injections for eulerian granular particles?
How do I access the theory manual for these models (DPM, eulerian) and related tutorials?

DPM particles have mass, just not volume. The diameter is used to calculate drag and in the collision checks.
Euler is a scalar based model which then includes terms to account for granular viscosity & temperature (friction & bounce) as well as a packing limit.
The button you're looking for is "Help" on the multiphase panel, or the "?" top right of the Fluent main window.

Where can I read more on eulerian granular injections?
Do you think it's possible to see particles deposition on surfaces for granular eulerian model?
I'd like to see if I can generate particle accumulation on surfaces using eulerian approach.

Please read up on the Eulerian Granular model. It doesn't use an injection as it's a scalar based approach: there are no particles as per the DPM model. DDPM may be appropriate, but again read up on the approach first.

Thanks, I see quite a few citations of Ansys FENSAP-ICE for ice accretion on aircraft wings. Is there a student version of FENSAP that I can access?

It looks like it's in the Student bundle. Note it's a specialised tool so may not be what you're after: it is for wing icing.
