Gridap provides a set of tools for the grid-based approximation of partial differential equations (PDEs) written in the Julia programming language. The main motivation behind the development of this library is to provide an easy-to-use framework for the development of complex PDE solvers in a dynamically typed style without sacrificing the performance of statically typed languages. The library currently supports linear and nonlinear PDE systems for scalar and vector fields, single and multi-field problems, conforming and nonconforming finite element discretizations, on structured and unstructured meshes of simplices and hexahedra.
- STABLE — Documentation for the most recently tagged version of Gridap.jl.
- DEVEL — Documentation for the in-development version of Gridap.
A hands-on user-guide to the library is available as a set of tutorials. They are available as Jupyter notebooks and html pages.
Gridap is a registered package in the official Julia package registry. Thus, the installation of Gridap is straight forward using the Julia's package manager. Open the Julia REPL, type ] to enter package mode, and install as follows
pkg> add Gridap- GridapGmsh Generate a FE mesh with GMSH and use it in Gridap.
- GridapMakie Makie plotting recipies for Gridap.
- GridapPardiso Use the Intel Pardiso MKL direct sparse solver in Gridap.
- GridapEmbedded Embedded finite elements in Julia.
- GridapODEs Gridap support for time-dependent PDEs.
- GridapDistributed Distributed-memory extension of Gridap.
These are some popular PDEs solved with the Gridap library. Examples taken from the Gridap Tutorials.
