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 |
| parallelInverseProduct | Parallelize the computation of the product J*M^{-1}*J^T where M is the matrix of the linear system and J is any matrix with compatible dimensions | 0 |
| verbose | Dump system state at each iteration | 0 |
| minSingularValue | Thershold under which a singular value is set to 0, for the stabilization of ill-conditioned system. | 1e-06 |
| conditionNumber | Condition number of the matrix: ratio between the largest and smallest singular values. Computed in method solve. | 0 |
