ESyS-Particle

velocity calculation

Asked by Jessica

Hello!!

I wanted to know how were the velocities over time was implemented in ESyS-particle. I am using a 3-dimensional silo flow and the incorporated interactions between unbonded particles as well between walls were rotational friction and aritficial viscosities (linear and rotational).

I am using the vector fieldsaver in obtaining the velocity data.

I guess that will be all!!

Thanks!!

Jessica

Not sure exactly what you mean by "how were the velocities over time was implemented in ESyS-particle".
If you like to know the details of the time integration scheme - its a simple, fully explicit first order scheme (see the CParticle::integrate and CRotParticle::integrate functions in Model/Particle.cpp and Model/RotParticle.cpp respectively). If that doesn't answer your question, could you specify it in abit more detail ?
