Detailed Description

A TriangulatedWall is a triangulation created from a set of vertices and a n-by-3 connectivity matrix defining n faces.

It is initialised by a unstructured grid vtk file:

TriangulatedWall w("TriangulatedWallSimple.vtk",speciesHandler.getLastObject());

w

RowVector3d w

Definition: Matrix_resize_int.cpp:3

TriangulatedWall

A TriangulatedWall is a triangulation created from a set of vertices and a n-by-3 connectivity matrix...

Definition: TriangulatedWall.h:31

The file consists of a set of vertices and a n-by-3 connectivity matrix defining n faces. Three vertices form a face; the face normal is oriented such that the vertices are ordered in anticlockwise direction around the normal.

Particles interact with a TriangulatedWall when they contact a face (from either side), a edge, or a vertex.

For a demonstration on how to use this class, see TriangulatedWallSelfTest (shown in the image below).

Member Function Documentation

◆ copy()

TriangulatedWall * TriangulatedWall::copy ( ) const

overridevirtual

Wall copy method. It calls the copy constructor of this Wall, useful for polymorphism.

Returns: pointer to a TriangulatedWall object allocated using new.

Implements BaseWall.

Reimplemented in WearableTriangulatedWall.

 {
     return new TriangulatedWall(*this);
 }

References TriangulatedWall().

◆ getDistanceAndNormal()

bool TriangulatedWall::getDistanceAndNormal	(	const BaseParticle &	p,
		Mdouble &	distance,
		Vec3D &	normal_return
	)		const

overridevirtual

Compute the distance from the wall for a given BaseParticle and return if there is a collision. If there is a collision, also return the normal vector.

Parameters

[in]	p	BaseParticle we want to calculate the distance and whether it collided of.
[out]	distance	The distance of the BaseParticle to this wall.
[out]	normal_return	If there was a collision, the normal vector to this wall will be placed here.

Returns: A boolean which says whether or not there was a collision.

This function computes whether or not there is a collision between a given BaseParticle and this TriangulatedWall. If there is a collision, this function also computes the distance between the BaseParticle and TriangulatedWall and the normal of the TriangulatedWall at the intersection point. It does this by calling TriangulatedWall::getDistanceAndNormal(const Vec3D& , Mdouble , Mdouble&, Vec3D&) const. Since this function should be called before calculating any Particle-Wall interactions, it can also be used to set the normal vector in case of curved walls.

NOTE: THIS ONLY RETURNS ONE OF POSSIBLY MANY INTERACTIONS; it's only used for finding out if interactions exist, so should be fine

Implements BaseWall.

 {
     Mdouble interactionRadius = p.getWallInteractionRadius(this);
     //it's important to use a reference here, as the faces use pointers
     for (const auto& face : face_)
     {
         if (face.getDistanceAndNormal(p, distance, normal_return, interactionRadius))
             return true;

◆ getInteractionWith()

BaseInteraction * TriangulatedWall::getInteractionWith	(	BaseParticle *	p,
		unsigned	timeStamp,
		InteractionHandler *	interactionHandler
	)

overridevirtual

Get the interaction between this TriangulatedWall and given BaseParticle at a given time.

Gets the interaction with this wall. In case of multiple contact points return the one with the shortest distance (i.e. largest overlap)

Parameters

[in]	p	Pointer to the BaseParticle which we want to check the interaction for.
[in]	timeStamp	The time at which we want to look at the interaction.
[in]	interactionHandler	A pointer to the InteractionHandler in which the interaction can be found.

Returns: A pointer to the BaseInteraction that happened between this wall and the BaseParticle at the timeStamp.

Reimplemented from BaseWall.

     Mdouble distance, minDistance = constants::inf;
     Vec3D normal, minNormal;
     Mdouble interactionRadius = p->getWallInteractionRadius(this);

◆ getName()

std::string TriangulatedWall::getName ( ) const

overridevirtual

Returns the name of the object, here the string "TriangulatedWall".

Returns: The string "TriangulatedWall".

Implements BaseObject.

Reimplemented in WearableTriangulatedWall.

 {
     return "TriangulatedWall";
 }

◆ move()

void TriangulatedWall::move ( const Vec3D & move )

overridevirtual

Move the TriangulatedWall to a new position, which is a Vec3D from the old position.

Parameters

[in] move A reference to a Vec3D that denotes the direction and length it should be moved with.

A function that moves the TriangulatedWall in a certain direction by both moving the walls and all intersections. Note that the directions of the intersections are not moved since they don't change when moving the TriangulatedWall as a whole.

Todo:: We should use the position_ and orientation_ of the TriangulatedWall; that way, TriangulatedWall can be moved with the standard BaseInteractable::move function, getting rid of an anomaly in the code and removing the virtual from the move function.

◆ write()

void TriangulatedWall::write ( std::ostream & os ) const

overridevirtual

Writes an TriangulatedWall to an output stream, for example a restart file.

Parameters

[in] os The output stream where the TriangulatedWall must be written to, usually a restart file.

Reimplemented from BaseWall.

Reimplemented in WearableTriangulatedWall.

     os << "Vertices " << vertex_.size();
     for (const auto& vertex: vertex_)
     {

◆ writeVTK()

void TriangulatedWall::writeVTK ( VTKContainer & vtk ) const

overridevirtual

adds extra information to the points and triangleStrips vectors needed to plot the wall in vtk format

Parameters

points	Coordinates of the vertices of the triangulated surfaces (in the VTK file this is called POINTS)
triangleStrips	Indices of three vertices forming one triangulated surface (in the VTK file this is called CELL)

Reimplemented from BaseWall.

 {
     const int s = vtk.points.size();
     for (auto v : vertex_)
     {
         vtk.points.push_back(v);
     }
     for (auto f : face_)
     {
         std::vector<double> cell;
         cell.reserve(3);
         cell.push_back(s + f.vertex[0] - &vertex_[0]);
         cell.push_back(s + f.vertex[1] - &vertex_[0]);
         cell.push_back(s + f.vertex[2] - &vertex_[0]);
         vtk.triangleStrips.push_back(cell);
