Spherical cutoff

WebNew atom- and group-based spherical-cutoff methods have been developed for the treatment of nonbonded interactions in molecular dynamics (MD) simulation. A new atom-based method, force switching, leaves short-range forces unaltered by adding a constant to the potential energy, switching forces smoothly to zero over a specified range.

In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane. If the plane passes through the center of the sphere (forming a great circle), so that the height of the cap is equal to the radius of the sphere, the … See more The volume of the spherical cap and the area of the curved surface may be calculated using combinations of • The radius $${\displaystyle r}$$ of the sphere • The radius $${\displaystyle a}$$ of the base of the cap See more Volumes of union and intersection of two intersecting spheres The volume of the union of two intersecting spheres of radii $${\displaystyle r_{1}}$$ and See more • Maths portal • Circular segment — the analogous 2D object • Solid angle — contains formula for n-sphere caps • Spherical segment • Spherical sector See more • Weisstein, Eric W.
