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 |
| iterations | Maximum number of iterations of the Conjugate Gradient solution | 25 |
| tolerance | Desired accuracy of the Conjugate Gradient solution evaluating: |r|²/|b|² (ratio of current residual norm over initial residual norm) | 1e-05 |
| threshold | Minimum value of the denominator (pT A p)^ in the conjugate Gradient solution | 1e-05 |
| warmStart | Use previous solution as initial solution | 0 |
| graph | Graph of residuals at each iteration | |
| nbThreads | If not yet initialized, the main task scheduler is initialized with this number of threads. 0 corresponds to the number of available cores on the CPU. -n (minus) corresponds to the number of available cores on the CPU minus the provided number. | 0 |
| taskSchedulerType | Type of task scheduler to use. | _default |
