Solidification with SPH pairstyle

Submitted by davidf on Sun, 01/08/2012 - 20:27

Hello dear liggghts community members !

I'm interested to simulate using the SPH pairstyle cooling and subsequent solidification of a mixture of 2 liquid phases.
I know there's a heat conduction fix in liggghts , but i'm not sure if the sph particle parameters actually depend on temperature\pressure so the material properties could change appropriately to liquid->solid phase transition.

Is liggghts capabale of simulating solidification ? What would be a good start towards this direction ?

Hi David,

>>Is liggghts capabale of simulating solidification ?
Not (yet)

>>sph particle parameters actually depend on temperature/pressure
Currently, they do not depend on temperature. But by implementing another euqation of state, it would be pretty easy to do this.

>>What would be a good start towards this direction ?
I have never investigated solidification with SPH, but I think it should in principle be doable. Maybe Andreas Aigner can give you hints how to proceed.
