This directory contains code for solving elliptic systems on our
($S^2$ topology) multipatch system in ../patch/.
The main files are as follows:
Jacobian.{hh,cc}
These define a Jacobian class. This is a generic interface
(a C++ abstract base class) to set up a Jacobian matrix and
solve linear systems with this matrix as the right hand side
matrix.
dense_Jacobian.{hh,cc}
These define a dense_Jacobian class (to store a Jacobian matrix
in a Fortran dense-matrix format) and a dense_Jacobian__LAPACK
class (to solve linear systems using LAPACK routines). These
classes are derived from (and hence share the generic interface
of) the Jacobian class.
row_sparse_Jacobian.{hh,cc}
These define a row_sparse_Jacobian class (to store a Jacobian
matrix in a row-oriented sparse-matrix format) and two different
linear solver classed derived from it:
row_sparse_Jacobian__ILUCG // ILUCG linear solver
row_sparse_Jacobian__UMFPACK // UMFPACK linear solver
lapack.h
Header file defining C/C++ prototypes for a few LAPACK routines.
lapack_wrapper.F77
Wrapper routines around a few LAPACK routines, to avoid problems
with C <--> Fortran passing of character-string arguments.
