• in 3D: 1) $x$-velocity, 2) $y$-velocity, 3) $z$-velocity, 4) $x$-angular velocity, 5) $y$-angular velocity, 6) $z$-angular velocity.

• in 2D: 1) $x$-velocity, 2) $y$-velocity, 3) angular velocity.

The return value is false for free and true for fixed conditions.

Returns:

b - fixity flag

Accepts:

b - fixity flag

Arguments:

b - rigid block pointer

i - integer degree-of-freedom
