fix deposit

Submitted by shokeyi on Thu, 11/22/2012 - 19:58

Hi everyone,

I am trying to deposit particles with the ''fix deposit'' command, but I do not know how to define the radius and density of the particle. I tried to use the ''create_atoms'' and ''set'' command, but the dump file shows the radius is not the same as I defined. Is there anyone know how to modify it?

Thanks.

Hi shokeyi,

fix deposit will set radius and density to default values (and you can use the set command to override it afterwards). Try using fix insert/pack or fix insert/rate/region (see examples), these commands can typically do everything you want from fix deposit for granular simulations

Hi Christoph,
Thanks for your reply. I will try this command. In addition, I use the ''fix gravity'' and ''create_atoms'' command to deposit, but it was deposit in a line not a cone I wanted. Do you know how to modify it?

In addition, I use the set command but only the radius and density of first atom is the one I set, others are the default values.
