HLS.js
HLS.js is a JavaScript library that plays HLS in browsers
HLS.js is a JavaScript library that implements an HTTP Live Streaming client. It relies on HTML5 video and MediaSource Extensions for playback. It works by transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. Transmuxing is performed asynchronously using a Web Worker when available in the browser. HLS.js also supports HLS + fmp4, as announced during WWDC2016. HLS.js works directly on top of a standard HTML<video> element. HLS.js is written in ECMAScript6... -

WingSegment
WingSegment: A tool for Analysis and Modeling of Insect Wings
...WingSegment detects cells, junctions, Pterostigma, and venation patterns, measuring geometric features and generating Voronoi patterns. The tool utilizes region-growing, thinning, and Dijkstra's algorithms for boundary detection, junction identification, and vein path extraction. It provides histograms and box plots of geometric features, facilitating comprehensive wing analysis. WingSegment's efficiency is validated through comparisons with established tools and manual measurements, demonstrating accurate results. The tool further enables exporting detected boundaries as FreeCAD macro files for 3D modeling and printing, supporting finite element analysis. ... -

2D Heat Transfer in .C
2D Heat Numerical Heat Transfer Solver
PLEASE NOTE: There is a complete installer available if you do not have CVI installed. If you do have it, you can simply download the source files and run them. The following program was built as a final evaluation project for Programming for Mechatronics Course for my BSc. in Mechanical Engineering. This solver is based around the Gauss-Seidel algorithm for 2D heat transfer for pre-determined boundary conditions (i.e. user defined temperatures). I hope this project will be useful for... -

F3DM
Finite Element Method on 3D Meshes
f3dmlib is a FEM library that can read, write and analyse 3D tetrahedral meshes, minimize a given functional, and refine the resulting meshes. The minimization is parallelized with OpenMP. Three main features in unstable 1.8.x version (available via GIT): quadratic elements, periodic boundary conditions, and the solver for scalar and electromagnetic wave equations. f3dmgeom is a collection of a few simple tools for creating surface meshes for tetgen. It can handle simple geometries only. -

RSchr-5
Solves one-electron Schrödinger equation, with SLEPc and PETSc
RSchr-5 calculates the smallest eigenvalues of the one-electron Schrödinger equation. The solved problem is defined on the finite domain, which is a box. The problem is solved with the zero Dirichlet boundary conditions. The implemented algorithm uses Finite Element Method with B-splines as basis functions. Disctretization leads to generalized eigenvalue problem. Program RSchr-5 solves the generalized eigenvalue problem by algorithms implemented in SLEPc amd PETSc libraries. It uses Krylov-Schur algorithm from SLEPc library. ... -

Ulambator
boundary element based flow solver for microfluidics
Ulambator solves the depth-averaged Stokes equations using a boundary element method. The combination of both reduces the discretization effort from 3D to 1D. Hence the flow solver is well adapted to free interface flows in shallow geometries. The manual and tutorial codes are still being extended. New functions will be made available. For more user information please check http://lfmi.epfl.ch/ulambator -

CFD2D
The incompressible Navier-Stokes equations solver in 2D domains
CFD2D is open source software for Linux for solving the non-dimensionalized incompressible Navier-Stokes equations (NSE) inside an arbitrary two-dimensional domain inscribed in a unit square with Dirichlet and "do-nothing" boundary conditions. The space discretization is based on Finite Element Method (FEM) using an approximately uniform triangular mesh. The two choices of FE spaces are offered, these are of the so called MINI-element and of the Taylor-Hood element. The first element consists of continuous piecewise linears with a cubic bubble function for the velocity field, and the second of continuous piecewise quadratics for the same. ... -

Isogeometric boundary element analysis with matlab
This code holds all the matlab files necessary to run a 2D isogeometric code for elastostatic analysis. For more guidance, it is probably a good idea to have a look through the code repository, and more recent updates to the code may also be present here. The main idea is that instead of using conventional Lagrangian polynomials to discretise the unknown fields and geometry (using the isoparametric concept), the basis functions that are used in Computer Aided Design (CAD) are used... -

Sketch a Frame
An iPad app that visualizes simple structural mechanics problems.
Sketch a Frame is an app where you can quickly draw a geometry and add forces and boundary conditions to visualize deflections, normal forces, moment distribution and normal tension. The app uses the finite element method (FEM) for the calculations. The elements are modeled as beam elements. This is a master thesis work by Daniel Åkesson for the department of structural mechanics at Lunds institute of technology.
