Description
|
||||
Generates streamline data by sampling a set of user-specified fields along a
|
||||
particle track, transported by a user-specified velocity field.

|
||||
lifetime | Maximum number of particle tracking steps | yes |
|
||||
trackLength | Tracking segment length | no |
|

nSubCycle | Number of tracking steps per cell | no|
|
||||
cloudName | Cloud name to use | yes |
|

|
||||
Note
|
