Scheme_EulerForward class

Contents

Description

This is a sub-class of the Scheme class for the implementation of the time integration scheme Forward Euler.

$$x_{i} = x_{i-1} + v_{i-1} \Delta t$$

$$v_{i} = v_{i-1} + a_{i} \Delta t$$

$$\theta_{i} = \theta_{i-1} + \omega_{i-1} \Delta t$$

$$\omega_{i} = \omega_{i-1} + \alpha_{i} \Delta t$$

$$T_{i} = T_{i-1} + \frac{\partial T}{\partial t_{i}} \Delta t$$

Notation:

$\Delta t$: Time increment

$x$: Coordinates

$v$: Translational velocity

$a$: Translational acceleration

$\theta$: Angular orientation

$\omega$: Angular velocity

$\alpha$: Angular acceleration

$T$: Temperature
