Smoothed Particle Hydrodynamics and Meshlless methods
 
Hello,

I've been following the forum for a while now (some weeks) and I saw that there are few threads on the SPH methods (actually on all meshless methods). I said to myself that maybe not everybody know what can and has already been done with such methods.

That's why I'm posting this link to the youtube channel of European Research Project NextMuSE in which I'm involded: http://www.youtube.com/user/nextmuse

If you want to know more about the project, I invite you to visit http://nextmuse.cscs.ch

Regards,

i'm doing meshless but not SPH.. and i'm interested to see how you and the research's group are going to defeat the weakness in numerical accuracy of SPH

I would advice you to take a look on the last decade developments on SPH and Meshless methods. I think you'll find some nice answers to your doubts.

I know how far SPH has developed since the first :D but still in the point of view of my supervisor, SPH is still inferior for turbulent flows' research but I do believe SPH is very powerful for multiphase and multiphysics ;) and in my opinion it still has common weakness shared with the other particle methods as the particles getting scatter.
well don't worry. i'm 100% pro to particle methods :)

anyway i'm doing vortex particle method

I like to say that I follow the philosophy that every family of methods has its field of applicability. And one must not overcome another...

For now SPH is not the most advised method (in my opinion) to study turbelence effects even though some may think otherwise. What we (our group) have in mind is that meshless methods are not here to replace FVM or FEM methods.

Anyways, I consider that some meshless method are mature enough to be applied to some fields of engineering. However, there is yet some development ahead of us.
