Python package for simulation of grain-based system using molecular dynamics method and agent-based model

module

• vect3
  • Vect3() Initialize with 3 arguments or none
  • strval() Get string value of Vect3 instance
  • add() Add two Vect3 instances
  • sub() Substract two Vect3 instances
  • dot() Dot product of two Vect3 instances
  • cross() Cross product of two Vect3 instances
  • mul() Multiply a scalar with a Vect3 instance (or vice versa)
  • div() Divide a Vect3 instance with a scalar
  • len() Get length or magnitude of a Vect3 instance
  • unit() Get unit vector of a Vect3 instance
  • neg() Set a Vect3 instance to opposite direction

usage

from butiran.vect3 import Vect3

a = Vect3(100.001, -0.5, 2021)
print("a = " + a.strval())

b = a.neg()
print("b = " + b.strval())

a = (100.001, -0.5, 2021)
b = (-100.001, 0.5, -2021)
