Pre-processing commands

• stickVerticesInClusters (double) Epsilon This command will add glued interfaces between bodies having the same cluster identifier. Only bonds between vertices (spheres) are added when the distance is less than Epsilon.

• stickClusters (double) Epsilon This command will add glued interfaces between bodies having different cluster identifier. Bonds are added when the distance is less than Epsilon.

• setAllVelocities (vec3r) velocity Set the velocity vector of all particles (that are not driven) to the prescribed value velocity.
