\section intro Introduction
|
|
|
|
IFEM is an object-oriented toolbox for implementing isogeometric finite element
|
|
solvers for linear and nonlinear partial differential equations.
|
|
The toolbox is developed through the ICADA project at SINTEF ICT, Trondheim.
|
|
The purpose of this code is to serve as a common base for isogeometric
|
|
PDE-simulators, using splines and NURBS as basis functions in the finite element
|
|
formulations. The toolbox contains methods for doing linear and non-linear,
|
|
stationary and dynamic time-domain analyses, as well as eigenvalue analyses.
|
|
|
|
\section overview Module overview
|
|
|
|
The simulation toolbox is organized into a set of modules,
|
|
organized as class hierarchies implemented in the C++ language.
|
|
The top-level driver is organized in the class SIMbase and its sub-classes.
|
|
These classes have methods for reading model data from an input file,
|
|
to assemble the linearized algebraic system of equations resulting from the
|
|
finite element discretization, and to solve that system.
|
|
It also contains methods for writing a VTF-file with results.
|
|
Problem-specific drivers and main programs are found in the sub-folder Apps.
|
|
|
|
The core of the finite element implementation is contained in the class
|
|
ASMbase and its sub-classes, which have methods for evaluating the element
|
|
matrices involved and assembling them into the system matrices.
|
|
There is typically one ASMbase object for each spline patch in the model.
|
|
|
|
The physical problem-dependent data and methods is accessed via an abstract
|
|
interface class, Integrand, through which the application programmer can
|
|
implement the weak form of the underlying finite element problem.
|
|
|
|
The actual splines evaluation is performed through the GoTools library, which is
|
|
not part of the current package. In addition, this code depends on the ARPACK,
|
|
LAPACK and BLAS libraries. Optionally, the SAMG algebraic multi-grid solver and
|
|
the SuperLU direct solver (public domain http://crd.lbl.gov/~xiaoye/SuperLU)
|
|
may be included. The Ceetron VTFAPI library may also be included for direct
|
|
export of simulations results to GLview VTF-files.
