Software Titles

  • BuckinghamPy: A Python software for dimensional analysis. The Buckingham Pi theorem is useful in determining the dimensionless terms that describe a physical phenomenon. The number of these terms grows with the number of variables. The traditional approach in identifying dimensionless quantities for a given system can be tedious and error-prone. BuckinghamPy is a Python software that automates the generation of all possible sets of dimensionless groups in LATEX format. BuckinghamPy serves as a helpful tool for experimentalists and engineers for both educational and research purposes. Release Date: 12/01/2021. Inventors: Mokbel Karam and Tony Saad.
  • PyModPDE: A python software for modified equation analysis. The modified equation is a useful tool in the analysis of numerical methods for partial differential equations (PDEs). It gives insight into the stability, diffusion, and dispersion properties of a given numerical scheme. Its derivation, however, is rather tedious and error-prone due to the enormous amount of algebra involved. PyModPDE is a python software that uses a novel approach to generate the modified equation. It takes a discrete PDE as its input and outputs the modified equation in LATEX format. We discuss the novel approach on which PyModPDE is based and then validate the software using one and two-dimensional PDEs. PyModPDE serves as an essential tool for computational scientists and engineers for both educational and research purposes. Release Date: 08/01/2020. Inventors: Mokbel Karam and Tony Saad.
  • MaxEnt. Given a finite number of moments that describe a distribution, there an infinite number of distributions that can produce that finite number of moments. This is known as the moment inversion problem: given a finite set of moments, how does one find the "one and only" distribution that produced these monents? MaxEnt uses the Shannon's maximum information entropy principle to reconstruct the most likely distribution given a finite set of moments. It argues that the likely distribution that produced these moments is the one that maximizes the information entropy - or the one that embodies whatever knowledge we have of the distribution. Release Date: 12/12/2018.
