SU2

SU2 is a suite of software tools written in C++ to numerically solve partial differential equations and perform PDE constrained optimization on unstructured meshes. The primary applications are computational fluid dynamics (CFD) and aerodynamic shape optimization, but it has been extended to solve problems in electrodynamics, chemical flows and other fields. proposal.md

Note that I am collaborating with Christina Wang on the future project. We are looking into pde solving packages for Julia/Python/Matlab. There are many options out there. Here is just one of the packages that we looked into. We are still considering options and we are open to suggestions, if anyone has them!

Gridap.jl

Gridap is a set of tools written in Julia. It allows a user to get an approximate solution to a PDE under various conditions such as unusual domains, multi-fields etc. It employs finite element methods. One of the prominent features is the ability to set up equations as they appear mathematically. This seems to reduce the number of code lines. The audience appears to be researchers who are familiar with mathematical frameworks (e.g. weak-form solutions) and need to solve their problems under above mentioned restrictions.

ASPECT

ASPECT is a code to simulate convection and tectonic processes in Earth and other planetary bodies, including applications for mantle convection, inner core convection, lithospheric scale deformation, two-phase flow, and numerical methods development. It is based on Deal.ii, a FEM library.

PETSc

In this project, I propose to analyze the performance of PETSc’s multigrid methods on various problems and compare them with other solvers. This will involve setting up problems, running solvers, benchmarking performance, comparing performance with other solvers, analyzing results, and documenting and sharing findings. This contribution will not only enhance our understanding of multigrid methods in PETSc but also help identify potential areas for improvement or optimization.

Firedrake

Firedrake uses the finite element method to automate the solving of partial differential equations. It enables high performance simulations for scientific applications, incorporating features like Unified Form Language to describe PDEs expressively, programmable solvers through coupling with PETSc, and many other interesting meshes and methods.

OpenFoam

OpenFOAM is a free, open source CFD software created to solve problems from complex fluid flows involving chemical reactions, turbulence and heat transfer, to acoustics, solid mechanics and electromagnetics. It is released every six months to include customer sponsored developments and contributions from the community. I'm planning on including the effects on diffusion given the phonon-electron interactions by adding a source term in the heat equation.

PyClaw

PyClaw is a Python based parallel solver for hyperbolic PDEs in 1D, 2D, and 3D. It has Riemann solvers that can solve problems including acoustic, advection, Burgers equation, Euler equations, shallow water equations, and etc. Examples and source code for solving the above problems are available.

OpenFOAM

Presentation

Presentation.pptx

OpenFOAM is an open source software based on the Finite Volume Method. It is used for solving complex multiphysics problems such as fluid flow, turbomachinery, heat transfer, diffusion, plane-strain elasticity, electromagnetism, etc. OpenFOAM has an active development community, although the contributions are controlled by the original authors of OpenFOAM and a few key contributors. Luis Rodriguez and I plan to contribute to OpenFOAM by modifying the thermal diffusion equation solver to include a finite thermal wave speed. This phenomenon is observed in cancer cells and human tissue, so modelling the heat transfer characteristics of such systems could offer insights into treatments involving laser heating.

SPECFEM2D simulates forward and adjoint seismic wave propagation in two-dimensional acoustic, (an)elastic, poroelastic or coupled acoustic-(an)elastic-poroelastic media, with Convolution PML absorbing conditions. The software SPECFEM also allows calculation for 1D and 3D model. My interest is surface wave, so I plan to use SPECFEM2D.

Thanks, everyone, for signing up. Counting above, we have

• 1 person who selected only Wednesday
• 8 people who selected only Friday
• 5 people who selected either.

Friday is going to be pretty full, so I'd like to ask that if you are willing to go Wednesday, please do. Further, if you're okay with presenting from my computer, please edit your comment above and link your presentation. I'll queue them all up before class. (If you choose a cloud slide tool like Google Slides or o365/Sharepoint Powerpoint, please remember to adjust the sharing so I can open it.) If you want to present from your computer, I'll ask you to run Zoom so you can screen-share and hopefully it'll be useful to distance viewers.

:three: SU2

SU2 is a suite of C++ tools designed to solve multiphysics analysis and optimization tasks on an unstructured grid. The software is primarily focused of CFD and aerodynamic optimization, but allows for rapid integration of new physics packages to expand beyond the original scope. proposal.md Graham-Bell_Presentation.pptx
