I would like to learn SPH and need Tutorials, introduction

Smooth Particle Hydrodynamics (SPH)

This begins with what SPH is and introduces the SPH theory and goes further into details,

HyperWorks Desktop Applications > HyperMesh > User's Guide > Meshing > 0-D Elements:

SPH Mesh

and its subtopics describe how to create SPH mesh and visualise them in HyperMesh,

here is another example apart from ditching,

Training Altair University > STRUCTURAL > ANALYSIS > PROJECTS (analysis) > Shock Tube

http://training.altairuniversity.com/structural/analysis/projects/shock-tube/

Once you start as above you can then go into the full theory of SPH in the RADIOSS theory manual for SPH,

navigate in help as User's Guide > What is Altair RADIOSS? > Block Format Input > Theory Manual:

Fluid and Fluid-Structure Simulation

and click on smooth particle hydrodynamics

Thank you,
exactly the beginners help, I was looking for !!!
Now I can dive into the SPH with Hypermesh/ Radioss!
