chrono::particlefactory::ChRandomShapeCreatorShavings Class Reference

Description

Class for generating worm-like particles, optionally helically twisted.

This can be used, for example, to generate shavings or chips as those created in milling and grinding processes, etc. This basic class uses a row of small spheres to approximate the chip shape, in sake of high computational performance in collisions etc.

SetSpheresSpacingFactor()

void chrono::particlefactory::ChRandomShapeCreatorShavings::SetSpheresSpacingFactor ( double  md )

inline

Since these worm-like structures are approximated with spheres, this settings tell how many spheres do you want along the line.

To keep things more intuitive, this 'spacing' value means the following: spacing between spheres = diameter * spacing_factor. The lower, the more precise the approximation, but the more the computational time for collisions. Usually, good values are in 0.4-0.8 range. The spacing might be adjusted automatically to match the end of the shaving, btw.
