Shiny-Sim is a molecular dynamics simulator, which allows to investigate the behavior of physical objects.
In shiny-sim I stick to two major objects
- PhysicalBodies - An physical object which can be described with its position and mass
- Interactions - describes the relation between two physical bodies, and exert on them force
The simulation of honeycomb structure in which one segment was initially moved in positive z direction.
- Python 2.7
- PyQt 4.10
- Numpy 1.8.1
- Scipy 0.13.3
% python main.py <grid_data> <init>Where is a list of physical bodies nad interactions between them. Description of physical body consist of kind of a PhysicalBody, followed by it x, y, and z coordinates and it's mass.
<PhysicalBody> <x> <y> <z> <mass>
Already implemented PhysicalBodies are
- Body
Description of interaction consist of Interaction, followed by indexes of Bodies it interacts with, and a value of a constant specific for given interaction.
<Interaction> <r_index> <l_index> <constant>
Already implemented Interactions are
- String
Body 50 50 0 10
Body 76 50 0 10
Body 128 50 0 10
String 0 1 10
String 1 38 10
String 2 3 10
It is also possible to move objects from their initial state using .
<operation> <index> <x> <y> <z>
move 38*18+18 0 0 1.5
move 38*18+19 0 0 1.5
move 38*19+17 0 0 1.5
Alternatively you can use grid_generator for creating grid data.
% python frid_generator.py <x_size> <y_size> <output> <configuration>where
- x_size - number of particles in a row
- y_size - number of rows
- output - output file
- configuration - one of the following options
- 0 - plain square grid
- 1 - plain honeycomb grid
