Pouring sand question

Hi all,
I am completely new to blender but not to 3d in general, I started using blender for its free physical simulation capabilities.
For a new project that I am working on I need to make a pouring sand simulation, I saw the following video but I have no idea how to achieve the result of the particles stack on top of each other.
Can someone please help me with this issue.

Thanks in advance.

Thank you very much for the informative tutorial, I’ve learned some very interesting things about fluids particles.
You can see what I am trying to achieve in the following link but as much as I try all I get is blob like simulation.
Can some one help me with the settings?
Thanks in advance.
