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 |
| filename | output VTK file name | |
| XMLformat | Set to true to use XML format | 1 |
| position | points position (will use points from topology or mechanical state if this is empty) | |
| edges | write edge topology | 1 |
| triangles | write triangle topology | 0 |
| quads | write quad topology | 0 |
| tetras | write tetra topology | 0 |
| hexas | write hexa topology | 0 |
| pointsDataFields | Data to visualize (on points) | |
| cellsDataFields | Data to visualize (on cells) | |
| exportEveryNumberOfSteps | export file only at specified number of steps (0=disable) | 0 |
| exportAtBegin | export file at the initialization | 0 |
| exportAtEnd | export file when the simulation is finished | 0 |
| overwrite | overwrite the file, otherwise create a new file at each export, with suffix in the filename | 0 |
Links:
| Name | Description |
|---|---|
| context | Graph Node containing this object (or BaseContext::getDefault() if no graph is used) |
| slaves | Sub-objects used internally by this object |
| master | nullptr for regular objects, or master object for which this object is one sub-objects |
