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 […]

There are different ways through which one can start to use latex for documentation. We can use Overleaf, sublime, atom , texstudio, Mactex, and many more for the same. I had tried using overleaf, sublime and texstudio for documentation and decided to use Sublime text editor because I found it convenient and easy. To start […]
Read MoreThis is purely based on my experience. I am listing some of the basic applications which may help the new researchers: Slack – New way to communicate with your team. It’s faster, better organized, and more user friendly. Gmsh – FE mesh generator. Paraview – Post-processing, results visualization Zotero – a free, easy-to-use tool to […]
Read MoreToday we are going to learn some important concepts related to matrix solvers. We will learn some of the preconditioners. They are often used as a black box in ABAQUS. We use its output ignoring the mechanism behind it. I hope with going through this blog post you will get a fair idea about the […]
Read MoreNow if you know anything about research, you will know that the first step and the only continuous step in every type or stream of research is READING. You start your research by reading hundred’s of journals, articles, web-pages etc… and you pursue your research by doing the same thing. Until you reach the end, […]

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 […]

Parallel computing is necessary for venturing into the world of high performance computing. Parallel computing as the name suggests allows us to run a program parallelly. The preferred language of choice in our lab is Python and we can achieve parallel computation in python with the help of ‘mpi4py’ module. This comes with the standard […]

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 […]

Goals for the second phase of the programming were two-fold: Create a method to construct MVC from arrays Develope code to test the integration of gmsh API with new mesh workflow. Creating MVC directly from arrays would allow bypassing saving of the mesh file onto the hard disk. The idea is to directly create MVC […]

XDMF stands for eXtensible Data Model and Format. This type of file format is used to store and exchange a large amount of scientific data between high-performance computing codes. FEniCS supports ‘io’ operations with XDMF file format which is further supported by the visualization tool of choice PARAVIEW. In this post, I would describe a […]
