^{PFHub: Phase Field Community Hub}

^{See the live website at pages.nist.gov/pfhub.}

Welcome to the PFHub wiki! The PFHub wiki is a place for anyone interested in the phase field benchmark project to add content. If you're new to the GitHub wiki, see the guide below.

Workshops

An integral component of the benchmarking effort are the twice yearly workshops. These workshops help to develop new benchmark problems and gather feedback on the existing problems.

• Workshop I; Jan 9-10, 2015; agenda.

• Workshop II; Oct 15-17, 2015; agenda, hackathon

• Workshop III; May 3-5, 2016; agenda, hackathon

• Workshop IV; Jan 18-20, 2017; agenda, hackathon

• Workshop V; Aug 1-3, 2017; agenda

• Workshop VI; Feb 20-22, 2018; agenda

• Workshop VII; Sep 25-27, 2018; agenda, presentations

Phase Field Benchmark / PFHub publications

The main task of the phase field working group is to generate phase field benchmark problems and create canonical solutions to these benchmarks. Here is a list of the publications concerning the benchmarks and associated website.

• Benchmark problems for numerical implementations of phase field models
• Phase field benchmark problems for dendritic growth and linear elasticity
• Phase field benchmark problems targeting fluid flow and electrochemistry
• Phase field benchmark problems for nucleation
• PFHub: The Phase-Field Community Hub

Phase Field Best Practices Guide

The phase field working group is developing a phase field best practices guide. The initial ideas for the guide are here.

Admin

• Note that the GitHub wiki does allow sub-directories, however, the page names are flat (i.e. each file name needs to be unique regardless of directory).
• Currently the sidebar is generated by hand, but probably github-wiki-sidebar looks like a good tool to automate this.

How to use this wiki

The best place to start is with the GitHub wiki docs. Please open an issue if you can't edit the wiki, but would like to. Remember that the GitHub wiki supports a variety of wiki markup, not just Markdown. Math isn't native to the GitHub wiki (or wasn't until very recently), see this stackoverflow question and this one. There are many solutions, however, the one that seems easiest is using the GitHub image math renderer. Basically, using this HTML snippet,

<img src="https://render.githubusercontent.com/render/math?math=e^{i \pi} = -1">

gives you

That approach is quite limiting, but will have to do for now. Apparently, there is now native support for maths, but this hasn't been deployed on the GitHub wiki yet :-(.
