Pencil Code school and 2025 user meeting

[Alberto Roper]

Dear all,

This is a reminder of the 2025 Pencil Code user meeting that will take place at CERN on October 27-31. You can find more information and registration at https://indico.cern.ch/e/PCUM2025

Please register as soon as possible to attend, and no later than September 28! If you have already registered and you would like to book a t-shirt, please send me an email (I have now just added the option in the registration form).

Also a reminder that this year we are organizing a Pencil Code school the week before the user meeting (October 20-24) focusing on early universe physics and gravitational waves, also at CERN. You can find the announcement of the school at the end of this email.

Thanks for your attention!

Best regards,

Alberto

Dear colleagues,

I apologize in advance if you are receiving this announcement multiple times.

This is an announcement of the Pencil Code school on early Universe physics and gravitational waves that will take place at CERN on the week of October 20-24. I would be grateful if you could forward this to interested students and young postdocs. The school targets early-career and senior researchers that are interested in learning and developing numerical skills applied to early Universe physics using Pencil Code (https://pencil-code.nordita.org/). The deadline for registration is approaching very soon: September 15th

If you are interested, please visit https://indico.cern.ch/e/PCUM2025

The school will take place the week before the 2025 Pencil Code user meeting (October 27-31). The purpose of the meeting is to bring regular users and core developers together to discuss scientific and technical progress since the last meeting, to instigate collaborative projects, and to allow new users to learn more about the code and to interact with other users and developers. Even if you are a new user attending the school, the user meeting can be a great chance to discuss with the developers and learn about the code! 

The lectures will cover numerical aspects:

• Introduction to Pencil Code: basic structure of Pencil Code, modularity, installation, compilation. Setting up parameters, defining initial conditions, boundary, conditions. Running the code and more!
• Numerical schemes for partial differential equations: numerical discretization of partial and ordinary differential equations in space and time.
• Post-processing and visualization of data with IDL and Python.
• Version control: contributing to Pencil Code, SVN and Github. Code testing, auto-tests.
• Parallelization on multiple CPUs and GPU acceleration of Pencil Code.

As well as applications to particular physics cases with hands-on exercises on:

• Magnetohydrodynamics of the early Universe
• Generation and evolution of primordial magnetic fields
• Chiral magnetohydrodynamics
• First-order phase transitions
• Gravitational wave production
• Axion inflation

With best regards,

Alberto Roper Pol
