Hi frnds,

I am working on DEM solver of STAR-CCM+. I created some particles of size of 0.01 m diameter. But when I am seeing in the scalar scene, it is not showing the actual size of the particle. As a result, it is looking so tiny as compared to the whole system that it is not possible to distinguish it.

Could any one help me that how can I see the original size of the particle.

With regards,

Chandi

Hi everyone,

I'm new to this forum and to CFD, I just started my master thesis for which I use StarCCM+.

I'm having the exact same problem as chandi, so I will use this thread instead of a new one, I hope that's ok. So perhaps someone of you could help me.

I did one of the DEM tutorials (Blast Furnace), but when it came to the simulation, the particles are not displayed in the structure as they should. When I switch the Point Scale Mode from Scalar to Pixel, I can see the particles as pixels, but when Scalar is chosen, nothing appears.

Does anyone of you have an idea what's the problem? Is this some known bug or could it be an issue with the graphics?

Thanks for any answer,
Doro

Hi ,

I am also trying to visualize the DEM particles in the domain but couldn't see them. If anybody know how to create the appropriate scene for seeing those particle help.

Thank You

Are you sure that the particles are being meshed properly?

In the scalar scene - outline and scalar properties you can change the representation of the selected part or region. If you can see the particles when represented as the original geometry and not as a meshed surface, it's probably a problem with your mesh.

Do we need to create spherical particle in our geometry as well as i went through the tutorial i found that we just need to specify particle diameter and it would be generated inside the region automatically....??

Did someone eventually got some hint about this issue, of particle representation in scene?
Thank you

Thank you

No solutions....i couldn't make what the previous post have tryed to explain.
