Potential Particles (DEM non-spherical particles)
Hi all,
I have commited the implementation of my previous published work with my
co-authors, Stefano Utili and Guy Houlsby here. It took some time to check
that it is still compatible.
C.W. Boon, G.T. Houlsby, S. Utili (2013). A new contact detection
algorithm for three-dimensional non-spherical particles. Powder
Technology, 248, pp 94-102. (PLEASE CITE)
Please let me know if it is available in the committed list. I am not too
familiar with github, and there were some complaints of too large file size
from my .vtk example, and I have deleted it, but it seems like this is in
the memory of github. But I believe other files are committed nicely.
How do I access onto YADE's website so that I can add a Section on how to
use the function?
There is an example file in trunks/examples/PotentialParticles. Note that
when defining the particle aabb is used to define the display, whereas
AabbRotated is used for bounding boxes. The vtk files can be opened with
ParaView-4.3. I have uploaded both my personal implementation and another
function to call an external library MOSEK. The latter is not mandatory
but helps in improving robustness. It is commented out. Please uncomment
it if you can link it to MOSEK (strongly recommended). I am not able to
check whether or not MOSEK's new release is still compatible with my old
one (ver 6), but it is not too difficult to update that part since it is
just passing of variables.
I have a full time job, and will not be able to respond immediately, but
will assist where possible.
Yours,
CW Boon
