Bare-bones SPH Simulation step-by-step

Asalih3d

Hello!

I've tried searching google but have not found anything useful as of yet. My question is, do anyone know of a paper which goes basically through, step-by-step, how to initialize and run a SPH simulation of like a dam-break or something similar simple in nature, ie. conduction of thermal energy?

I am trying to understand the programming aspect more thoroughly and I would like to start with the bare minimum, since it is difficult for me to dissect/understand the DualSPHysics code properly.

Python/Matlab examples would be preferred

Kind regards

If you're familiar with Fortran, I suggest you start from SPHysics2D.

This guy developed his own solver and if you go to Section 3, he explains briefly what he did. (It's in C++). Use the second link for the source code.

Lastly,

This one is not as advanced as DualSPHysics, but it's pretty easy to follow and it's written in Phyton.

I don't know if those answer your question but good luck!

Thank you, will have a look!

This is just a reference point and not a guide, but this PDF from David Bindell at Cornell University provides some pieces of MATLAB code which might ease the translation of more thorough guides, in case examples in those guides are given in statically-typed & lower-level languages.

Thank you very much :-)
