Summary changed to:
what are the differences of YADE with PFC version 6 in simulating?
Description changed to:
Hi there
I know that PFC version 6 has the capability of simulating angular rigid
blocks. This is a step forward in being able to model tightly interlocked, low
porosity assemblies and it prepare conditions to study in a more efficient and
robust way. Rigid, convex {polyhedral in 3D; polygonal in 2D} blocks are now
available in PFC 6. We can easily create a zero porosity initial specimen, bond
and cut the material, and allow for failure and flow. I believe that there are
several benefits to the rigid blocks in PFC, including: 1) ability to couple
with FLAC3D, 2) robustness of the contact detection and resolution, 3)
efficiency especially during flow, 4) block rounding, 5) ability to model in 2D
and 3D with nearly the same data files, 6) Python bindings to the rigid block
data structures.
Please compare capabilities of YADE with PFC version 6 in the above cases. Does
YADE software have those abilities and capabilities which I mentioned in
previous paragraph? which one of them is in YADE? what is the disadvantages of
YADE compared to PFC (6)?
The previuos version of PFC (version 5) approach has a key shortcoming
which is the inability to specify very low initial porosities for the
choke blasted blasted ring material due to the spherical or clump shape
of the particles.
I wait for your useful comment and analogies

As for this comment, it is very hard to make any kind of comparisons. What length scale are you using angular rigid blocks for? If you use angular rigid blocks as a discretization of space, I see no difference compared to spheres. At that scale we aren't modeling anything directly. I added a functionality to Yade's PFV to consider this type of scenario [1]. As for interlocking, could you comment on how blocks might provide a more accurate representation of reality compared to an increase of contact detection radius for a body [2]?

Question #676507 on Yade changed: https://answers.launchpad.net/yade/+question/676507 Status: Open => Answered Robert Caulk proposed the following answer: Hello, I have a question for you, it seems PFC is providing the exact functionality you need, so why are seeking a replacement? Anyways, it's always a good exercise to find out which functionalities are "sorely" missing from one code or another, so let's discuss! >>1) ability to couple with FLAC3D, Depends on the FLAC3D interface. Yade was coupled with Escript [1] >>2) robustness of the contact detection and resolution, Please elaborate. Yade's contact detection is quite robust. >>3) efficiency especially during flow, What kind of flow? CFD? Does PFC have a 3D PFV model like Yade? >>4) block rounding, What is that? >>5) ability to model in 2D and 3D with nearly the same data files, What is that? >>6) Python bindings to the rigid block data structures. Yade is fully wrapped in Python. Every object can be exposed to Python. >>Yade can simulate model in 100*50*20 m dimensions? Sure.
