Application¶

Modules management¶

GALAMOST is a modular program. Application manages and calls modules and run simulation. Usually, we only define an application object in the context of script. The modules can be added add() into or removed remove() from the application before runing run() the simulation.

class Application(all_info, dt)

The constructor of an application object.

Parameters: all_info (AllInfo) – system information dt (float) – integration time step
add(boost::shared_ptr<*> object)

adds an object to the application.

remove(boost::shared_ptr<*> object)

clear()

removes all objects from the application.

setDt(float dt)

sets integration time step.

run(unsigned int N)

runs the simulation for N time steps.

Example:

dt = 0.001
app = galamost.Application(all_info, dt)
# builds up an application.
app.run(10000)
# runs the simulation for 10000 time steps.


Multi-stage simulation¶

An application can have single or multiple stage simulations. The commands in the context of script are executed sequentially. Every stage simulation is achieved with run(). Before a stage of simulation, the modules and parameters can be adjusted. New modules can be added into the applicaitons by add(). The added modules at last stage can be removed from the application, otherwise they will be kept. For example:

• First stage simulation:

dt = 0.001
app = galamost.Application(all_info, dt)

app.remove(lj)
