SimuLab 12: Changing Particle Movement

1. Start growing a new pattern by choosing Clear from the Edit menu, then choose Split from the same menu. This creates a new window showing a duplicate of the initial seed.


2. For this second pattern, click on the Straight button under Particle Movement. In the "straight'' setting, each particle moves in a straight line but in a direction that is chosen randomly.


3. Click Go to start movement in this second window.


4. Now click on the first window and click Go. Click on one window then the other, changing the speed of each so that the two patterns grow at approximately the same rate. As each pattern grows, keep it all on screen by moving the Cell Size slider to the left.


5. Using the Straight setting, can you make a pattern that is similar to the result of your electrodeposition experiment? If so, save it as an image file for later analysis.

Q4.15: Compare the growths for the Random versus Straight settings: How is the movement of the particle different? Does the pattern grow in more steps or fewer steps? Is the pattern more leggy or more compact?
