rblock.scalesphere

Syntax

b = rblock.scalesphere(rb,f)

Scale the rigid block to an equivalent sphere. The rigid block is scaled so that its {area in 2D; volume in 3D} is the same as a {circle in 2D; sphere in 3D} of diameter f. The pebbles are scaled, their positions are modified, and the volume is updated.

Note

• If the volume or moment of inertia has been previously specified by the user either via rblock attribute or via FISH (rblock.vol, rblock.moi.prin.real, or rblock.moi.real), the principal moment of inertia is in a fixed state and will not be scaled. See the rblock.moi.fix intrinsic for further details.

Returns:

b - boolean indicating success/failure of operation

Arguments:

rb - rigid block pointer

f - diameter of {a circle in 2D; sphere in 3D}
