Density Dependence

Hello - I'm new to the list and the software, but looking forward to discussions with users.
I'm attempting to use individual based modeling techniques to simulate an eelgrass meadow. Portions of the individual shoot's behavior will be dependent on how many neighbours it has within a specified area. Does anyone have tips on how to create a list for each individual of its number of neigbours? Any assistance will be greatly appreciated!

This is the sort of problem you'd normally solve by adding an association submodel to represent connections between individual members of a population. A 'neighbour' association would have an existence condition based on the distance between the individuals on either side, with perhaps a check to see that individuals do not appear as their own neighbours. There is some help on association submodels in the help files included with Simile, but it might also be worth looking at examples from our model library -- use the keyword 'Association submodel'.

Hope this helps

thanks

Jasper - Thank you for the advice, I was thinking along those lines but examples are always the best way for me to see how to make these things work!
