# Appendix B¶

In this appendix we present alphabetical list of CellG attributes:

clusterId - cluster id

clusterSurface - total surface of a cluster that a given cell belongs to. Needs ClusterSurface Plugin

ecc - eccentricity of cell . Needs MomentOfInertia plugin

extraAttribPtr - a C++ pointer to Python dictionary attached to each cell

flag - integer variable - unused. Can be used from Python

fluctAmpl - fluctuation amplitude. Default value is -1

iXX - xx component of inertia tensor. Needs MomentOfInertia Plugin

iXY- xy component of inertia tensor. Needs MomentOfInertia Plugin

iXZ- xz component of inertia tensor. Needs MomentOfInertia Plugin

iYY- yy component of inertia tensor. Needs MomentOfInertia Plugin

iYZ- yz component of inertia tensor. Needs MomentOfInertia Plugin

iZZ- zz component of inertia tensor. Needs MomentOfInertia Plugin

id - cell id

lX - x component of orientation vector. Set by MomentOfInertia

lY - y component of orientation vector. Set by MomentOfInertia

lZ - z component of orientation vector. Set by MomentOfInertia

lambdaClusterSurface - lambda (constraint strength) of cluster surface constraint.Needs ClusterSurface Plugin

lambdaSurface - lambda (constraint strength) of surface constraint. Needs Surface Plugin

lambdaVecX - x component of force applied to cell. Needs ExternalPotential Plugin
