Hello everyone


Im now studying on the simulation of the sinterering process of microparticle silver. Because of the big size of particles, I need to use the ATC package. I want to treat the interconnected part between particles by using MD and the other part by using FE (as shown in the figure below). Do you think that my problem can be solved with this package please ?

​that is impossible to say at this level of generality. how large are the particles and what is the time scale of the process you are looking at?
unless i miss my guess, i would expect, that those length and time scales are too far apart to make the kind of model you propose practical. if you want to make some experiment, you should look for something much simpler.

you may also want to do some research of the published literature into available mesoscale models. it looks to me, that what you need could be something conceptually similar to either lattice-boltzmann or peridynamics, or perhaps there might be a suitable formulation for either of them, that you could use.
