In this grasshopper example file you can simulate a spin force by defining a polar field.
In this grasshopper definition, you can use the Nursery plugin to simulate a parametric freeform vector field.
In this grasshopper definition, we will use the Nursery plugin to simulate a force field which is actually a noise affecting a series of meshes.
In this grasshopper definition we have used the Boid plugin and Nursery plugin combined to simulate sliding of a series of particles on a surface.
In this grasshopper definition we have used a mesh to create a force field using the Nursery plugin.
Nursery by Gwyllim Jahn is a behavioural design framework for Grasshopper. It consists of a set of tools for creating Agents and Behaviours and executing these behaviours on a multithreaded simulation core.
