Comments

frankie March 07, 2008, at 09:24 AM: This required a rewrite of the plume comm mechanism. The good news is that this new method is much better, requiring only one way communication. That means that the sim code no longer requires any "Get" calls from the graphics, except during initialization of course. Rewrite of the code was required in both the doug plume scripts and on the simulation side.

frankie April 24, 2008, at 12:17 PM: The new logic requires a setting for the minimum time in milliseconds for a plume to be on (basically to garuantee that it is seen). This is going to be set via an environment variable "PLUME_MIN_TIME_ON" so that users can override it in their user_env.csh file. We are going to default it to 50 ms. More details in the EDGE v2.0 release notes.
