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 |
positions | If not set by user, find the context mechanical. | |
triangles | If not set by user, find the context topology. | |
quads | If not set by user, find the context topology. | |
volume | The volume is only relevant if the surface is closed. | 0 |
update | If true, will update the volume at each time step of the simulation. | 0 |
