I wanna model the proppant placement in the hydraulic fracture using molecular dynamics, but I am the beginner of MD, I read some articles about the modelled shape of research object (mainly, parallel plate, or rectangular object ), by contrast, the shape of sphere is relatively spare. Besides, I wanna to model large particles, the size of proppant is usually between 0.5-1 mm, how to realise this condition (using coarse-grained MD)?
Dear Ma,
Although, I am not pretty sure what is the power of your computational system, your considered model size is too large to simulate by MD. However, I heard that smoothed particle hydrodynamics might be more suitable than MD for your project, although I have no idea about coarse grained MD. But, I think coarse grained MD is also similar to smoothed particle hydrodynamics method.
Bets regards,
Bahman
MD simulation methods are not able to simulate such a system for you.
Dear Ramin
Why is that? Is that because the limitation of spatial scale of MD?
Regards
Dear Ma,
I also checked the coarse grained MD which is usually applied for macromolecules. So, again I think that your system size is too large to simulate by MD. why you do not check the SPH?
Regards,
Bahman
