Problem to creat cone wall!

Submitted by DependOnMe on Tue, 12/18/2012 - 15:51

Hi,all
I have a question. I want to simulate particles pouring into a cone. But some problems really confused me!
From the manual on this website :http://nf.nci.org.au/facilities/software/LIGGGHTS/doc/fix_wall_gran.html, I should make the input script like this:
fix conewall all wall/gran/hertz/history 0 0 zcone 0 0.2 0.05 0.1 1
But the LIGGGHTS tells me that "Need to use define style 'mesh' or 'primitive' (fix_wall_gran.cpp:224)"
So I changed the script like this（Learn from the input examples）：
fix conewall all wall/gran/hertz/history primitive type 1 zcone 0 0.2 0.05 0.1 0.0 0.0
But still I can't make it! The Error message is "unknown primitive wall style"
Is anything wrong ?
I can't find the problem ! (By the way the LIGGGHTS version is LIGGGHTS-PUBLIC 2.2.1)
Can anyone help me ? Thanks a lot !

Looks like it has been left out during the conversion from 1.5.3 to 2.x. There isn't an option for it in the primitive_wall_definitions.h file. I think the documentation just needs to be updated to remove that reference. If you want to use a cone, I think you'll need to create external CAD and use a mesh wall.

Regards,
Chris

Chris:
Thank you very much! I don't understand why they leave the cone out from the wall/gran command. But that's ok, I will learn to use a mesh wall imported from CAD.
It looks like that the manual document from that website is out of data!

It's simply a matter of priotrity... there hasn't been a high priority in implementing the cone wall in 2.X, but others (like the cylinder) have been extended. Anyway, it would be just a few lines of code to re-add the cone wall

Cheers, Christoph

every time i used zone, it went wrong.
in addition, i can't use .stl file in both in.liggghts_init and in.liggghts_run
