Maximum number of drifters

What is the maximum number of drifters that can be used in LPT? When I used more than 10,000 particles, it runs but cannot open the model results.


Hi Amir,

EFDC doesn’t have problem simulating any number of drifter particles. But EE might have some memory issues when you have very large number of particles (>10000). The reason that EE struggles to display the results for large number of particles is because EE loads all the results of all the particles in memory before it starts displaying the tracks of the drifters. For example, you can view the particles by elevation, by layers and also view the entire track of the particles. So, having large number of particles might cause memory issues. The coming new release (EFDC Plus) will eliminate this issue.
