# 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. |
