[CSC 335] Project 2 and Extra Credit

[Andrew J. Pounds]

  I know that some of you are working on project 2 this weekend (which 
is wise).  I wanted to give some of you a heads up that are also working 
on the extra credit for project 2.

For some of the smaller room sizes the "simulated seconds" (not the 
actual runtime) will generally be between 50 and 200 seconds.   The 
actual runtime will vary based on the number of divisions you have in 
each dimension.

Now if you add a barrier (as required by the extra credit) you will have 
MUCH longer runtimes to completion (I'm talking hours to days here).   
However, you can still glean off the important information by stopping 
the simulation after a certain number of seconds.

For example, in the following simulation I placed a barrier that was 
open on both ends, but filled the room from top to bottom.  I then 
started the simulation with chemical in the upper corner of the room.   
Here is the contour plot result taken from the middle of the room after 
50 seconds of simulation time:

no barrier

Here is the same room, with the same conditions as above, but this time 
with the barrier that I mentioned above.

Clearly the model is working -- but I did not have to allow the second 
simulation to run to its "completion".

Let me know what questions you have.
