Member Function Documentation

double Edge2D::getPressure

(

)

const

Get pressure on the edge from interaction forces

Referenced by getScalarFieldFunction().

Here is the caller graph for this function:

Edge2D::ScalarFieldFunction Edge2D::getScalarFieldFunction

(

const string &

name

)

[static]

Get the Edge2D member function which returns a scalar field of a given name. Returns NULL if a field with that name doesn't exist.

Parameters:

name	the name of the field

References getPressure().

Here is the call graph for this function:

Edge2D::VectorFieldFunction Edge2D::getVectorFieldFunction

(

const string &

name

)

[static]

Get the Edge2D member function which returns a vector field of a given name. Returns NULL if a field with that name doesn't exist.

Parameters:

name	the name of the field

Referenced by TSubLattice< T >::addVectorTriangleField().

Here is the caller graph for this function:

void Edge2D::moveNode	(	int	id,
		const Vec3 &	d
	)

Move one of the corners. The identifier for the corner is the global node id. If the node with the id is not in the edge do nothing.

Parameters:

id	the global id of the node to be moved
d	the amount of movement

void Edge2D::print

(

)

output Edge2D to cout

Vec3 Edge2D::toGlobal

(

const Vec3 &

p

)

convert point in local coords to global coords

Parameters:

p	the point in local coords

Referenced by BEdge2DInteraction::calcForces().

Here is the caller graph for this function:

Vec3 Edge2D::toLocal

(

const Vec3 &

p

)

convert point in global coords into local (x,y,0) coords

Parameters:

p	the point in global coords

Referenced by BEdge2DInteraction::BEdge2DInteraction().
