Member Function Documentation

computeVolume()

double MeshLib::PointRule1::computeVolume ( Node const *const * element_nodes )

static

Calculates the length of a line.

Definition at line 20 of file PointRule1.cpp.

{
    return 0;
}

identifyFace()

unsigned MeshLib::PointRule1::identifyFace ( Node const *const * element_nodes, Node const * nodes[1] )

static

Returns the ID of a face given an array of nodes.

Definition at line 32 of file PointRule1.cpp.

{
    if (nodes[0] == element_nodes[0])
    {
        return 0;
    }
    return std::numeric_limits<unsigned>::max();
}

isPntInElement()

bool MeshLib::PointRule1::isPntInElement ( Node const *const * nodes, MathLib::Point3d const & pnt, double eps )

static

Checks if a point is inside the element.

Parameters

pnt	a 3D MathLib::Point3d object
eps	tolerance for numerical algorithm used or computing the property

Returns

true if the point is not outside the element, false otherwise

Specifically this function tests if the squared euclidean distance between the points nodes and pnt is less then eps.

Parameters

nodes

the nodes of the element.

Definition at line 25 of file PointRule1.cpp.

{
    double const dist = MathLib::sqrDist(*nodes[0], pnt);
    return (dist < eps);
}

References MathLib::sqrDist().

validate()

ElementErrorCode MeshLib::PointRule1::validate ( const Element * e )

static

Tests if the element is geometrically valid.

Definition at line 42 of file PointRule1.cpp.

{
    ElementErrorCode error_code;
    error_code[ElementErrorFlag::ZeroVolume] = hasZeroVolume(*e);
    return error_code;
}
