Welcome to c/cfd

Feel free to post anything related to Computational Fluid Dynamics (CFD).

Questions, discussions, reviews, interesting articles, job postings, and project showcases are all welcome!

This is currently a work in progress, content suggestions are highly appreciated. The goal is for this post to become a helpful summary of all important things related to CFD.

Resources:

(please suggest other good resources - journals, videos or yt channels, courses paid or free, articles, books, docs, wikis, forums, etc.)

1. CFD Online: One of the best sites for CFD

Tools

(M=macOS, W=Windows,L=Linux)

All-in-one:

• ANSYS Fluent (via ANSYS Workbench) (Paid) (L,W,M): very widely used CFD software

• SimFlow, a GUI for OpenFOAM (Paid with a limited free version) (L,W)

• dicehub (Paid) (online): cloud-based platform for CFD simulations

• COMSOL Multiphysics (Paid) (L, M, W)

• SimScale (Paid with a limited free version) (L, M, W, online): cloud-based simulation platform

• STAR-CCM+ (Paid) (L,W): commercial CFD software from Siemens

Note: A lot of the open source tools below integrate well with each other. So they can together form a good free, open source alternative to the above tools.

CAD:

• FreeCAD (FOSS) (L, M, W)

Solvers:

• OpenFOAM: a powerful command-line tool for CFD (FOSS) (L,M,W)

• SU2 (FOSS) (L, M, W) - An open-source suite for multiphysics simulation

Post-processing:

• ParaView (FOSS) (L, M, W): A powerful open-source application for visualizing and analyzing scientific data; commonly used for CFD results.

• VisIt (FOSS) (L, M, W)

Nutomic:

This is implemented in the main branch now. If you want to develop a plugin for Lemmy, have a look at the RFC and the examples. If you have questions about plugin development, feel free to post in the Matrix dev chat, ![email protected] or open an issue.

https://github.com/LemmyNet/lemmy/issues/3562#issuecomment-2760779122

Examples in multiple languages: https://github.com/LemmyNet/lemmy-plugins#lemmy-plugins (only a few examples currently, more languages are possible including Python)

Anyone planning to start working on a plugin?

has anyone tried it on wayland? are there any other screensavers for wayland? AFAIK this is the only screensaver that works on wayland.

v2.8, v2.9, v2.10 were all released recently after a few months hiatus (v2.7 was in Oct).

Most of the changes were bug fixes but v2.8 had new features too:

• New visibility mode: Intelligent Auto Hide (aka Intellihide / Dodge Windows): in this mode, the dock only hides itself when there's a window covering it or there's a maximized window.
• Supports LXQt (KWin) on Wayland: including special menu entries (e.g. Log Out), specific default launchers, setting wallpapers and separate config.
• Task icon: Allow cycling backwards through window applications with CTRL: so left-clicking cycles forwards and CTRL + left-clicking cycles backwards.

Crystal Dock is a cool dock (desktop panel) for Linux desktop, with the focus on attractive user interface, being simple and easy to customize, and cross-desktop support.

The current version (version 2) supports KDE Plasma 6 and LXQt (KWin) on Wayland. Other desktop environments will be considered when they run on Wayland and provide sufficient APIs. The previous version (version 1) supports KDE Plasma 5, GNOME, LXQt, Cinnamon and MATE on X11.

I would like to backup some KDE settings but don't really know which files to copy from .config

Searching for their names in github.com/KDE has given me some idea about their purposes but I couldn't find any comments or documentation there either.

For context Autin (Github) is a shell history replacement that apparently provides a lot of extra functionality.

Has anyone used it? Im thinking of switching to it but Im worried about its impact on performance and if its worth it.

I remember first hearing about it a few years back but after that I didn't hear anything about it again so I decided to check. Seems like its still under development. I would have built it but the source code is ~6 gb which is probably too much for my relatively dated computer (to build).
