PVFMM README File
*****************
PVFMM Version 1.0.0 is the latest release (January 2014)
WHAT IS PVFMM?
==============
PVFMM is a library for solving certain types of elliptic partial
differential equations.
* We support Stokes, Poisson, and Helmholtz problems on the unit
cube, with free-space or periodic boundary conditions, with
constant or mildly varying coefficients. Our method is based on
volume potential integral equation formulation accelerated by the
Kernel Independent Fast Multipole Method.
HOW TO GET PVFMM
================
For the latest stable release of PVFMM
<URL: padas.ices.utexas.edu/pvfmm.tgz>
LICENSE
=======
PVFMM is distributed under the LGPLv3 licence. See COPYING in
the top-level directory of the distribution.
INSTALLING PVFMM
================
To install PVFMM, follow the steps in the INSTALL file, which is
located in the top directory of the source distribution.
USING PVFMM
===========
The file examples/Makefile can be used as a template makefile for any
project using the library. In general the MakeVariables file should
be included in any makefile and CXXFLAGS_PVFMM and LDFLAGS_PVFMM should
be used to compile the code.
Two very simple examples illustrating usage of the library are available:
For particle N-body : examples/src/example1.cpp
For volume potentials: examples/src/example2.cpp
To compile these examples:
make examples/bin/example1
make examples/bin/example2
* The volume potentials example will take a long time, the first time
it is used, since it has to precompute quadrature rules. This data
is saved to a file and used for subsequent runs. See INSTALL for
the configure option '--with-precomp-dir=DIR' to set the default
path for precomputed data.
