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.
