CentPack is a collection of freely distributed C++ libraries that
implement a number of high-order, non-oscillatory
central schemes for hyperbolic systems of conservation laws in one- and two-space dimensions,
ut + f(u)x + g(u)y= 0.
Only information specific to the problem
to be solved needs to be provided, namely, an external subroutine description of the flux functions
f(u) and g(u), together with the
appropriate initial and boundary conditions.
In this distribution of CentPack we provide the core files that implement
the family of fully-discrete one-dimensional schemes of
Nessyahu and Tadmor (.pdf),
the corresponding second-order two-dimensional extension of Jiang and
and several implementations of the semi-discrete formulation of Kurganov and Tadmor
in one- and two-space dimensions. All the packages of this distribution --
pre-compiled binaries and
source code alike,
include a set of auxiliary sample files. These should allow the user to: (i) easily create a sample application to solve several hyperbolic models, and
(ii) use them as a template to generate his/her own auxiliary files as needed for the application sought.
Precompiled Binaries: At
the present, we offer precompiled CentPack libraries for Mac
OS/X and Linux operating
