rblock scale command
Syntax
- rblock scale keyword ... <range>
Primary keywords:
Scale rigid blocks. If the volume or moment of inertia has been previously specified by the user either via the
rblock attribute
command or via FISH, the principal moments of inertia are in a fixed state and will not be scaled. This can be modified with FISH (see therblock.moi.fix
intrinsic for further details). One can either scale the volume to a target value, the volume to the volume of an equivalent {disk with unit thickness in 2D; sphere in 3D} with a specified diameter, or via the return value of a FISH function.- diameter fdiam
Scale the rigid block to have volume of an equivalent {disk with unit thickness in 2D; sphere in 3D} with a specified diameter.
- fish-size sfish fval
Use the FISH function with name sfish to scale the “size” of the rigid block to fval. The FISH function must take a single argument that is a rigid block pointer and return a floating point value corresponding to a linear measure of the rigid block size.
- keep-inertial
Scale the rblocks for contact detection but keep the volume and moment of inertia unchanged from before scaling.
