Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM = ELEMENT_DIM>
class OffLatticeSimulation< ELEMENT_DIM, SPACE_DIM >

Run an off-lattice 2D or 3D cell-based simulation using a cell-centre- or vertex-based cell population.

In cell-centre-based cell populations, each cell is represented by a single node (corresponding to its centre), and connectivity is defined either by a Delaunay triangulation or a radius of influence. In vertex- based cell populations, each cell is represented by a polytope (corresponding to its membrane) with a variable number of vertices.

The OffLatticeSimulation is constructed with a CellPopulation, which updates the correspondence between each Cell and its spatial representation and handles cell division (governed by the CellCycleModel associated with each cell). Once constructed, one or more Force laws may be passed to the OffLatticeSimulation object, to define the mechanical properties of the CellPopulation. Similarly, one or more CellKillers may be passed to the OffLatticeSimulation object to specify conditions in which Cells may die, and one or more CellPopulationBoundaryConditions to specify regions in space beyond which Cells may not move.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void OffLatticeSimulation< ELEMENT_DIM, SPACE_DIM >::AddCellPopulationBoundaryCondition ( boost::shared_ptr< AbstractCellPopulationBoundaryCondition< ELEMENT_DIM, SPACE_DIM > >  pBoundaryCondition)

Add a cell population boundary condition to be used in this simulation.

Parameters:
pBoundaryConditionpointer to a boundary condition

Definition at line 86 of file OffLatticeSimulation.cpp.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void OffLatticeSimulation< ELEMENT_DIM, SPACE_DIM >::AddForce ( boost::shared_ptr< AbstractForce< ELEMENT_DIM, SPACE_DIM > >  pForce)

Add a force to be used in this simulation (use this to set the mechanics system).

Parameters:
pForcepointer to a force law

Definition at line 74 of file OffLatticeSimulation.cpp.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
c_vector< double, SPACE_DIM > OffLatticeSimulation< ELEMENT_DIM, SPACE_DIM >::CalculateCellDivisionVector ( CellPtr  pParentCell) [protected, virtual]

Overridden CalculateCellDivisionVector() method for determining how cell division occurs. This method returns a vector which is then passed into the CellPopulation method AddCell(). This method may be overridden by subclasses.

For a centre-based cell population, this method calculates the new locations of the cell centres of a dividing cell, moves the parent cell and returns the location of the daughter cell. The new locations are found by picking a random direction and placing the parent and daughter in opposing directions along this axis.

For a vertex-based cell population, the method returns the zero vector.

Parameters:
pParentCellthe parent cell
Returns:
a vector containing information on cell division.

Todo:
Could remove this dynamic_cast by moving the code block below into AbstractCentreBasedCellPopulation::AddCell(), allowing it to be overruled by this method when overridden in subclasses. See also comment on #1093.
Todo:
do something for vertex models here
