◆ setupInitialConditions()

void HorizontalMixer::setupInitialConditions ( )

inlineoverridevirtual

This function allows to set the initial conditions for our problem to be solved, by default particle locations are randomly set. Remember particle properties must also be defined here.

A virtual function with no implementation but can be overridden.

Todo:: I (Anthony) wants to change this to be an external function. This has a lot of advantages especially when using copy-constructors. This is a major change and will break other codes, so therefore has to be done carefully.

This sets up the particles initial conditions it is as you expect the user to override this. By default the particles are randomly distributed
