Detailed Description

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

An abstract cell-based simulation class. This class contains common functionality from off lattice and on lattice simulations.

The AbstractCellBasedSimulation 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 CellKillers may be passed to the AbstractCellBasedSimulation object to specify conditions in which Cells may die,

Subclasses use one or more Force laws or update rules (Which are passed to the child class object) to define the mechanical properties of the CellPopulation.

◆ DoCellBirth()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
unsigned AbstractCellBasedSimulation< ELEMENT_DIM, SPACE_DIM >::DoCellBirth ( )
protectedvirtual

During a simulation time step, process any cell divisions that need to occur. If the simulation includes cell birth, causes (almost) all cells that are ready to divide to produce daughter cells.

If mOutputDivisionLocations is set to true, then this method also writes the location of each cell division at the present time to mpDivisionLocationFile. This outputs a line of tab-separated values of the form: [time] [div 0 x-pos] [div 0 y-pos] [div 0 z-pos] [div 0 age] [div 1 x-pos] [div 1 y-pos] [div 1 z-pos] [div 1 age] ...

with [y-pos] and [z-pos] included for 2 and 3 dimensional simulations, respectively, and [...age] denoting the age of the dividing cell.

Returns
the number of births that occurred.

If required, output this location to file

◆ SetupSolve()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM = ELEMENT_DIM>
virtual void AbstractCellBasedSimulation< ELEMENT_DIM, SPACE_DIM >::SetupSolve ( )
inlineprotectedvirtual

A method for subclasses to do something at before the start of the time loop.

Reimplemented in OffLatticeSimulation< ELEMENT_DIM, SPACE_DIM >, OffLatticeSimulation< 1 >, OffLatticeSimulation< 2 >, and CryptSimulation2d.

Definition at line 224 of file AbstractCellBasedSimulation.hpp.

◆ Solve()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void AbstractCellBasedSimulation< ELEMENT_DIM, SPACE_DIM >::Solve ( )

Main Solve() method, used to evolve the cell population. Note that prior to calling Solve() we must have called SetEndTime(). We may also have optionally called SetDt(); if not, then a default time step is used.

The Solve() method proceeds as follows.

Setting up:

First, we set up SimulationTime, which (i) provides a globally consistent time, accessible to all other classes in the cell_based code and (ii) handles any rounding issues when the time step does not exactly divide the end time.

Next, we create output files. We then call SetupSolve(), which is empty in the parent class but may be overridden, e.g. to open additional output files. We then call SetupSolve() on any member objects inheriting from AbstractCellBasedSimulationModifier. This class hierarchy allows the user to introduce new ways of updating the cell population within the simulation.

Next, we set up each cell by calling ReadyToDivide() on it, which updates the cell's age and cell cycle model. Finally, we call WriteVisualizerSetupFile() and OutputSimulationSetup(), as well as WriteResultsToFiles() on the cell population, to record the initial configuration. This completes the set up process.

The main time loop:

At each time step, we begin by calling UpdateCellPopulation(), which implements any cell deaths and cell divisions through DoCellRemoval() and DoCellBirth() respectively. We then update the correspondence between cells and the mesh by calling Update() on the cell population.

If mOutputCellVelocities is set to true and we are at a printing time, then we als write the velocity of each cell at the present time to mpCellVelocitiesFile. This outputs a line of tab-separated values of the form: [time] [cell 0 x-pos] [cell 0 y-pos] [cell 0 z-pos] [cell 0 x-vel] [cell 0 y-vel] [cell 0 z-vel] ...

with [y-pos] and [z-pos] included for 2 and 3 dimensional simulations, respectively, and data for cells being ordered as given by the cell population Iterator.

Next, we call UpdateCellLocationsAndTopology(), which is pure virtual in the parent class so must be overridden. As the cell population has been updated, we then increment SimulationTime by one time step. We then call UpdateAtEndOfTimeStep() on any AbstractCellBasedSimulationModifiers present, e.g. to write additional output. In an analogous manner to the calls to SetupSolve() prior to entering the main time loop.

The last step within the main time loop is to output the present results to file.

Finishing up:

After exiting the main time loop, we call UpdateCellPopulation() in order to carry out a final update of the cell population. We also call UpdateAtEndOfSolve()} on any member objects inheriting from AbstractCellBasedSimulationModifier in an analogous manner to the aforementioned calls to SetupSolve() UpdateAtEndOfTimeStep(). Finally, we close output files. This completes the Solve() method.

◆ StoppingEventHasOccurred()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
bool AbstractCellBasedSimulation< ELEMENT_DIM, SPACE_DIM >::StoppingEventHasOccurred ( )
protectedvirtual

A child class can overload this if they want the simulation to stop based on certain conditions before the specified end time (for example, run until a crypt becomes monoclonal).

Returns
true if stopping event has occurred

Definition at line 600 of file AbstractCellBasedSimulation.cpp.

◆ UpdateCellLocationsAndTopology()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM = ELEMENT_DIM>
virtual void AbstractCellBasedSimulation< ELEMENT_DIM, SPACE_DIM >::UpdateCellLocationsAndTopology ( )
protectedpure virtual

Update the cell locations and topology (connectivity) of the cell population. This method is called within the main time loop of Solve() .

As this method is pure virtual, it must be overridden in subclasses.

In the case of an OffLatticeSimulation, the method computes the force acting on each node (corresponding to a cell in centre-based models and to a vertex in vertex-based models) and integrates equations of motion to find the new position of each node.

In the case of an OnLatticeSimulation, the method performs Monte Carlo updating of the cell population, through a call to UpdateCellLocations() on the cell population object.

Implemented in OffLatticeSimulation< ELEMENT_DIM, SPACE_DIM >, OffLatticeSimulation< 1 >, OffLatticeSimulation< 2 >, and OnLatticeSimulation< DIM >.

◆ UpdateCellPopulation()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void AbstractCellBasedSimulation< ELEMENT_DIM, SPACE_DIM >::UpdateCellPopulation ( )
protectedvirtual

Calls the deaths, births and (if mUpdateCellPopulation is true) CellPopulation::Update() methods.
