Here I demonstrate how to animate the force field to produce a delay in the destruction of a fractured wall. This is a technique I used to produce some variation in the scene of the destruction of a fractured wall structure. The resulting visual effect has a huge hole that gets blasted through the wall and slowly destroys the rest of the wall pieces as the force field grows in its animation.

Demonstrates how to setup a simple basic RBD (rigid body dynamic) dopnet simulation scene in Houdini with glue constraints. The glue strength is adjusted to a level that withstands the gravity. This is a perfect starting point or template that can be used as a starting point before adding more complex forces.

Constraints in Houdini define how a piece of geometry behave and how they move in the simulation when external forces are exerted upon them. Glue & Spring Constraints both behave differently in the simulation.

Destruction Simulations are controlled by the way you fracture the geometry being destroyed and how the glue constraints are to be broken on impact. Check out this video, where I covered the basics of setting up a destruction simulation using glue constraints provided by the voronoi fracture and I covered some basic concepts for glue constraints, to understand some fundamentals.
