Hi Luis,

You can probably configure the tool’s parameters to give you want you want, but it depends on exactly what that is.

If you just want to drift larvae without having them settle, you could try adjusting the Settlement Rate parameter to be extremely low (e.g. 0.000000000000001). That would still allow some settlement, but it would be a tiny amount. To restrict it even further, you could define a very small patch—just a single pixel—at the edge of the study area as remotely as possible. Then list this patch as the only one under the Patches That Larvae Can Settle On parameter. It will receive a tiny amount, but the vast majority of larvae will just drift.

If your species does not spawn in defined places, just everywhere, you could define two patches. The first would be the small remote one at the edge of the study area, listed under Patches That Larvae Can Settle On. The second would be a huge patch that takes up the rest of the study area, which you would list as the only patch under Patches That Disperse Larvae. In theory, this should create a huge, uniform cloud of larvae at the start of the simulation and then drift them, with some small amount settling on that remote patch.

You’d have to play around with the tool to see if this would work. I’m not sure if it will accept only having one patch where larvae can settle. It should be ok, but you’d have to try it.

All the best,

Jason
