Read MoreFEniCSx is the new version of FEniCS that is currently actively developed. Dolfin-x is the computational environment of FEniCS and implements the FEniCS problem-solving environment in Python and C++. New features in Dolfin-x in addition to existing features of Dolfin include: Variational formulations with complex numbers support Support for quadrilateral and hexahedral elements Higher-order […]
Read MoreIn FEniCS we have an option of importing the mesh geometry in .xdmf format. This makes our job much more easier and simpler. As it allows us to use different packages (Gmsh, Ansys, Abaqus etc) for complex geometry modeling and meshing. Check this post to know how to use Nastran file (.bdf) from Ansys to […]
Read MoreThere are many ways in which we can obtain the weak form and the strong form. We focus on the Variational Principles to derive them because FEniCS works on the variational form
Read MoreIn FEniCS, we can either work with the inbuilt meshes or we can also import the mesh file generated in another pre-processing tool as a xdmf format. In order to create inbuilt meshes, firstly, dolfin module is imported as: Matplotlib library is used to display the mesh plots. The different types of inbuilt meshes in […]
Read MoreBoundary conditions (B.C.) are constraints necessary for the solution of a boundary value problem. A boundary value problem is a differential equation (or system of differential equations) to be solved in a domain on whose boundary a set of conditions is known. Boundary value problems are extremely important as they model a vast amount of […]
Read MoreThrough this post, you will learn how to do basic vector and matrix operations through petsc4py and how to solve a small linear problem using petsc4py. In addition, FEniCS PETSc formats and conversions are also briefly mentioned.
