How can I increase the resolution of my output?

#1

As soon as I further reduce the size of the grid, the system hangs up and I am unable to extract the result. Please find the attached files for your reference. (Honey bee, Ladybug). As a new user I cant upload the grasshopper file. Please find a screenshot for reference.

@Eashita The value of grid-size is the key of the calculation time. It depend on the memory of your computer.
Another suggest for you:set True for parallel will decrease the running time.
