Data

Name Description Default value
name object name unnamed
printLog if true, emits extra messages at runtime. 0
tags list of the subsets the object belongs to
bbox this object bounding box
componentState The state of the component among (Dirty, Valid, Undefined, Loading, Invalid). Undefined
listening if true, handle the events, otherwise ignore the events 0
rayleighStiffness Rayleigh damping - stiffness matrix coefficient 0
poissonRatio FEM Poisson Ratio in Hooke's law [0,0.5[ 0.45
youngModulus FEM Young's Modulus in Hooke's law 5000
initialPoints Initial Position
method "small", "large" (by QR), "polar" or "svd" displacements large
localStiffnessFactor Allow specification of different stiffness per element. If there are N element and M values are specified, the youngModulus factor for element i would be localStiffnessFactor[i*M/N]

updateStiffness update structures (precomputed in init) using stiffness parameters in each iteration (set listening=1) 0
Visualization
drawHeterogeneousTetra Draw Heterogeneous Tetra in different color 0
showStressColorMap Color map used to show stress values Blue to Red
showStressAlpha Alpha for vonMises visualisation 1
