I would like to learn SPH and need Tutorials, introduction

Good morning,
I like to learn/ start with SPH method (smooth particle hydrodynamics) ,
therefore I'm looking for an introduction into SPH and simple tutorials.
(I have FEM-, but no CFD- background)

In the Altair tutorials I can find the boat ditching ( RD3580 ).

Are there any more descriptions/ introductions/ help available?
Do you know good articles / books?

Thanks, Dirk
