Ball Sims

SIM_ball_L1

This is a simulation of a ball under the influence of a force field. The force on the ball is of constant magnitude, and always directed toward a fixed point.

Inputs

Parameter	Units	Default
ball.force.input.origin[2]	m	{ 0.0, 2.0 }
ball.force.input.force	N	8.0
ball.state.input.mass	kg	10.0
ball.state.input.speed	m/s	2.0
ball.state.input.elevation	rad	45 ° x (180/π)
ball.state.input.position[2]	m	{ 5.0, 5.0 }

Outputs

Parameter	Units
ball.state.output.position[2]	m
ball.state.output.velocity[2]	m
ball.state.output.acceleration[2]	m

SIM_ball_L2

This simulation is a derivation of SIM_ball_L1. It uses Trick "dynamic-events" to simulate walls, off of which the ball can bounce.

Inputs

(In addition to those of SIM_ball_L1) These parameters define the coordinates of the walls.

Parameter	Units	Default
ball.force.input.floor_y_pos	m	-10.0
ball.force.input.right_wall_x_pos	m	10.0
ball.force.ceiling_y_pos	m	10.0
ball.force.left_wall_x_pos	m	-10.0

The outputs are the same as those of SIM_ball_L1.

SIM_ball_L3

This simulation is a derivation of SIM_ball_L2. The SIM_ball_L3 S_define instanciates two ballSimObject's rather than just one.
