doubt in multisphere

Submitted by Srivathsa91 on Sat, 11/07/2015 - 23:42

Hi,

I am very new to multisphere model. I would like to know,

1) Is their a way to model two or more different "types" of particles in a single clump?
2) How can I model in different shapess?

Thank you.

I could understand how to create different shape of clumps.
fix pts1 all particletemplate/multisphere 1 atom_type 1 density constant 2500 nspheres 4 ntry 1000000 spheres 0. 0. 0. 0.005 0.004 0.0066025 0. 0.005 -0.004 0.0066025 0. 0.005 type 1
(((( triangular shape ))))

Please help me in modelling different types of particles in a single clump.

Thank you

Since you know the command to define a multisphere particle ...
You define in that line the material type of the whole clump. There is no way implemented to define different types. Sry no better news.

To be honest there are barely cases where this is useful. There is no relative motion and no interaction between the particles. One possible scenario would be a hard and a soft side of a particle, but as mentioned before that is not implemented.
