Detailed Description

object for flexible representation of a mass matrix.

NAME: MassMatrix - object for flexible representation of a mass matrix

DESCRIPTION:

The class "MassMatrix" is a trivial encapsulation of a "MatDiag" matrix with assembly and solve functionality.

Constructor & Destructor Documentation

MassMatrix::MassMatrix ( )

There is only one constructor which takes no arguments.

MassMatrix::~MassMatrix ( ) [inline]

Member Function Documentation

MatDiag(NUMT) & MassMatrix::M ( )

const MatDiag(NUMT) & MassMatrix::M ( ) const

bool MassMatrix::isLumped ( ) const [inline]

bool MassMatrix::make ( FEM & simulator,

GridFE & grid )

calls "FEM makeMassMatrix" for computing the mass matrix. On repeated calls, "make" does only compute a new matrix if the number of nodes is changed. The return value is true if real computations have taken place (false indicates that the an already computed mass matrix can still be utilized).

void MassMatrix::solve ( const Vector(NUMT) & rhs,

Vector(NUMT) & x )

soles the system "M*x=rhs" by trivial Gaussian elimination when "M" is of type "MatDiag".
