Data:

Name Description Default value
name object name unnamed
printLog if true, emits extra messages at runtime. 0
tags list of the subsets the objet 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
isCompliance Consider the component as a compliance, else as a stiffness 0
rayleighStiffness Rayleigh damping - stiffness matrix coefficient 0
tetrahedronInfo Internal tetrahedron data
method "small", "large" (by QR) or "polar" displacements large
poissonRatio FEM Poisson Ratio 0.45
youngModulus FEM Young Modulus 5000
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]
updateStiffnessMatrix 0
computeGlobalMatrix 0
HyperReduction
prepareECSW Save data necessary for the construction of the reduced model 0
nbModes Number of modes when preparing the ECSW method only 3
modesPath Path to the file containing the modes (useful only for preparing ECSW) modes.txt
nbTrainingSet When preparing the ECSW, size of the training set 40
periodSaveGIE When prepareECSW is true, the values of Gie are taken every periodSaveGIE timesteps. 5
