If you are developing your own numerical software applications,
Habanera can increase your productivity by providing high-quality
software components. At this time, Habanera is developing two C++
toolkits, named Jem and Jive, that are briefly described
below. Please contact us if you are interested in using them, or if
you like to know more.
Jem
The C++ toolkit Jem provides a set of classes and functions that
facilitate the development of robust, modular software. In
particular, it provides classes for:
- dynamic memory management;
- storing and manipulating multi-dimensional arrays;
- reading and writing data in various formats;
- serializing graphs of objects;
- building common data structures (lists, hash tables, etc.);
- reading program configuration data;
- writing parallel programs;
- and for building 3-D visualization applications.
Jem also provides a set of classes and functions that hide
system-dependent programming interfaces. Consequently, an
application built on top of Jem can easily be ported from one
operating system to another.
Jive
Jive is a programming toolkit that is aimed at solving partial
differential equations (PDEs). It provides a set of classes and
functions and data structures for transforming a PDE into a system
of equations; for solving such a system of equations; and for
computing quantities derived from the solution. In particular, Jive
provides classes for:
- storing and building grids and meshes;
- storing and building (sparse) matrices;
- solving systems of equations;
- evaluating shape functions and integrals;
- finding objects near a point;
- adding and deleting degrees of freedom on the fly;
- running simulations on parallel computers;
- making checkpoints (enabling restarts);
- and for visualizing results in real time.
Jive is not a ready-to-run program that computes an answer given a
set of input parameters. To make use of Jive you will have to write
your own program -- or modify one of the example programs that come
with Jive -- that computes the solution of a particular PDE. This
may take a bit more time than simply starting a ready-to-run
program, but it also enables you to tailor your program to the PDE
to be solved. What is more, Jive enables you to solve virtually any
type of PDE whereas a ready-to-run programs are restricted to a
limited set of PDE types. In fact, Jive is currrently being used to
solve PDEs arising in fluid dynamics, solid mechanics, particle
dynamics, stochastic material analyses, among others.
