Data Structure of FEM in FEniCS

Storing the element connectivity, element nodes, nodal degrees of freedom etc.. are of significant importance in any numerical package which implements finite element analysis. And this constitutes the data structure of FEM. In this post, I will try to explain how FEniCS does this.

Demystifying DOCKER – II : The FEniCS Workflow

Part I : Demystifying DOCKER – I : The What and How Now that the idea and use of docker is clear, and that docker is installed and running; let us see how to make use of it to run FEniCS based codes in your system. FEniCS is a popular open-source computing platform for solving […]

Demystifying DOCKER – I : The What and How

Docker is a set of coupled software-as-a-service and platform-as-a-service products that use operating-system-level virtualization to develop and deliver software in packages called containers. The software that hosts the containers is called Docker Engine. If you are like me and didn’t understand any word of the above sentence, WELCOME, you are in the right place !!! […]

How to add a FEniCS shell module in Docker file

Docker is a set of coupled software-as-a-service and platform-as-a-service products that use operating-system-level virtualization to develop and deliver software in packages called containers. The software that hosts the containers is called Docker Engine. In our lab we mostly use the open source tool FEniCS for computation. FEniCS is a open source library, that is maintained […]

How to visualize which part of mesh is with which processor

In our research we come across many high scale problem which need to be solved, and it is very important that the approach should be efficient. One of the way by which we can run a program parallelly. In our lab we commonly use Python language and FEniCS for computation. How to do parallelization for […]

FEniCS is incredible!

I have been using FEniCS in my research for the past two years, and I have to say that it is just pure gold in scientific computing with differential equations. It helps you think way beyond the constructions of domain-specific implementations of finite element method. You will not understand its powers until you have faced […]

Parallel Computing with FEniCS

Parallel computing refers to breaking down a larger problem into independent smaller parts that can be executed simultaneously by multiple processors. The result is generated by combining results from all processors. It saves a lot of time and money compared to serial computing, where only one instruction is executed at any moment of time. In […]

FEniCS: The mesh workflow

This is my final post for the GSoC2019 program. The primary goal of the project was to ensure that the meshing package of choice gmsh, DOLFIN, and the preferred visualization package, Paraview work seamlessly together. The intention was to make improvements to the process of preserving the information about tagged regions of the mesh when importing it […]
