Material for the 13th SPHERIC International Workshop in Galway, 26-28 June 2018

The 13th SPHERIC International Workshop in Galway, 26-28 June 2018, is the annual global forum for development and applications of Smoothed Particle Hydrodynamics and related methods. Join us on Ireland's Atlantic Coast to share the latest advances in SPH. In addition, the optional training day on 25 June offers an intensive introduction to the theory and application of SPH.

13th SPHERIC International Workshop website

wikipedia general info

• wikipedia is a wiki site. Interesting wikis (for us):
  • Encyclopedia of Mathematics. See e.g. Navier Stokes equations
  • SklogWiki, statistical mechanics and thermodynamics
  • CFD wiki at cfd-online
  • each github project gits its on wiki, automatically. E.g. DualSPHysics.
• Its markup language is wikitext (see below, Editing).

Editing

Here's a cheatsheet . Also, from WP:SC, WP:CHEAT

Sectioning and TOC

Use ==...==, with more equal signs as sections go deeper.

TOC is automatic. This has been shown to save lives .

Wikilinks

• They may be written (often, guessed), as [[...]]. E.g. used extensively in wikipedia and other wiki pages.
• More readable wikilinks from piping, as [[ wiki_entry | printed_text ]]. E.g. Galway's name derives from a princess'

HTML links

• These are just straight http(s)://... . E.g. https://www.upm.es
• Short links: [ http(s)://... ]. E.g. [1]
• Readable HTML links, no vertical bar! [ http(s)://... printed_text ]. E.g. don't mix London Times with New York Times

Bibliography

This is a bit more cumbersome. See official instructions .

Usually, at the end one writes

== References ==
{{Reflist}}

Each reference is a footnote, created as <ref>...</ref>. For example:

• Introduced by in 1977<ref>L.B. Lucy, ''A numerical approach to the testing of the fission hypothesis'', Astron. J., Vol 82, pp. 1013–1024, 1977</ref>, and by ...
• Introduced by Gingold and Monaghan in 1977, and by ...

For repeated citations, a nickname may be chosen to identify the inline citation, with <ref name="nickname" >...</ref>. E.g.

• ... and by Gingold and Monaghan <ref name="gm1977" >R.A. Gingold and J.J. Monaghan, ''Smoothed particle hydrodynamics: theory and application to non-spherical stars,'' Mon. Not. R. Astron. Soc., Vol 181, pp. 375–89, 1977</ref>, the same year.
• ... and by Gingold and Monaghan , the same year.

Later on, you can just say <ref name="name" /> (yes, it self-closes)

• Viscosity was not discussed in <ref name="gm1977" />, but was later introduced ...
• Viscosity was not discussed in , but was later introduced ...

Mathematics

See the official math reference . In a nutshell, LaTeX is used for formulas, which permits easy copy-and-pasting between different environments (LaTeX in article, blogs, other wikis, beamer presentations, markdown ...).

E.g. Cauchy momentum equation (conservation form)

${\frac {\partial }{\partial t}}(\rho \,\mathbf {u} )+\nabla \cdot (\rho \,\mathbf {u} \otimes \mathbf {u} )=-\nabla \cdot p\,\mathbf {I} +\nabla \cdot {\boldsymbol {\tau }}+\rho \,\mathbf {g} ,$

where u is the flow velocity, ∇∙ is the divergence.

Some style conventions (see the manual of style) :

• Equations should be indented with a ":" at its beginning
• Inline formulas are better typed as {{math|'''u'''}}, which produces u, or u (notice the latter is sans-serif).
• Equations may be numbered, with {{NumBlk}} and {{EquationRef}}, and later referred to with {{EquationNote}}.

For example: {{NumBlk|:|<math> \nabla\cdot\bathbf{u}= 0</math>|{{EquationRef|1}} }}

$\nabla \cdot \mathbf {u} =0$ (1)

Later on, the text can refer to this equation by its number using syntax like this:

As seen in equation ({{EquationNote|1}}), blah blah blah...

The result looks like this:

As seen in equation (1), blah blah blah...

Pictures

Infoboxes.

Figures can be uploaded to wikipedia or wikimedia commons. The latter is quite strictly public domain, only! If you upload own work onto it, it enters the common domain. It already stores common images, such as portraits. Let's look for e.g. George Gabriel Stokes, and we find https://commons.wikimedia.org/wiki/File:George_Gabriel_Stokes.jpg .

Then, simply

Collapsable material

The visible title of the collapsible stuff
This is the collapsible stuff, which may of course include equations $V_{\mathrm {g} }=\iint dx\,dy\;\int _{0}^{\eta }dz\;(\rho -\rho ')gz={\frac {1}{2}}(\rho -\rho ')g\iint dx\,dy\;\eta ^{2},$ and references (which will be outside, at the main Reference section).

Documentation

This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.

To change this template's initial visibility, the |state= parameter may be used:

• {{Ddcampayo|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
• {{Ddcampayo|state=expanded}} will show the template expanded, i.e. fully visible.

Editors can experiment in this template's sandbox (create | mirror) and testcases (create) pages.
