PetIGA: A framework for high performance Isogeometric Analysis

Overview

This software framework implements a NURBS-based Galerkin finite element method (FEM), popularly known as isogeometric analysis (IGA). It is heavily based on PETSc, the Portable, Extensible Toolkit for Scientific Computation. PETSc is a collection of algorithms and data structures for the solution of scientific problems, particularly those modeled by partial differential equations (PDEs). PETSc is written to be applicable to a range of problem sizes, including large-scale simulations where high performance parallel is a must. PetIGA can be thought of as an extension of PETSc, which adds the NURBS discretization capability and the integration of forms. The PetIGA framework is intended for researchers in the numeric solution of PDEs who have applications which require extensive computational resources.

Installation

After installing PETSc, set appropriate values for PETSC_DIR and PETSC_ARCH in your environment:

$ export PETSC_DIR=/home/user/petsc-3.3-p3
$ export PETSC_ARCH=arch-linux2-c-debug

Clone the Mercurial repository hosted at Bitbucket

$ hg clone https://bitbucket.org/dalcinl/PetIGA

Finally, enter PetIGA top level directory and use make to compile the code and build the PetIGA library:

$ cd PetIGA
$ make all
$ make test
