With active simulation <-> time analysis synchronization, tasks (if time-relevant and without a predefined target time) in task groups are scaled proportionately with MTM-UAS times.
In the event that the human model is not located above a floor object during simulation, the value of the Default floor height [mm] is used. The entered value can be considered as virtual, invisible floor at this height.
By indicating the Cell size in collision grid [mm], the length and width of the collision grid cells is defined. A small cell size results in an increased requirement for (working) memory and an increased duration of calculation as well as more precise results in the collision prevention; whereas larger cells reduce the memory requirement and the duration of calculation, but provide less precise results.
The Preset safety distance during walking [mm] sets the default value for the distance to the object's bounding box for the calculation of automatic targets (default is 250 mm).
The parameter Bounding volume adjustment [mm] makes it possible to modify the bounding box or detail bounding volume globally. The specified value adjusts the volume expansion in all three dimensions. Positive values are increasing the bounding box, while negative values are reducing it.
The option Use 3D walk path calculations makes it possible the switch between 2D and 3D walk path calculations.
The option Process dynamic targets enables or disables support for moving (walk-)target computations. The checkbox must be active when the dynamic objects (see chapter Taskk library / Tasks (basic objects) / Complex object DOF (Degrees of Freedom)) with sensors linked need to be simulated. Otherwise the linked sensors are ignored.
By setting the parameter Use references always as new parent objects, when placing an object during simulation it will be automatically kept beneath the defined reference object in the object hierarchy. The functionality corresponds to the task parameter New parent object and user can again overwrite this (see chapter Task library / Object handling / Place objects).
The activation of the field Ignore reach space limitation during simulation deactivates the reach limitation of the human model.
The option Allow walk targets in collision geometry makes it possible to execute a walk path despite a collision at the target point of a walk task. Collision objects on the path are still detected.
Using Advanced collision avoidance the collision avoidance feature could be turned on/off for the entire project.
Collision between human models while walking could be avoided by activating the checkbox Collision avoidance between human models. This could have an influence in the process time and walk path length.
If the collision avoidance between human models is activated, the field User defined worker to worker safety distance [mm] is active, in which you can type in the distance between human models.
By activating Full squatting only, the human model will squat down completely if it is necessary to lower the centre of gravity of the body. If the parameter is deactivated, the corresponding squatted intermediate positions will also be calculated.
Reach space visualization smoothness [%] is a value to control the accuracy of the reach space computation. The higher the input value, the more accurate is the computed reach space. But the associated computation time will also be higher.
It is possible to Prevent time-scaling of walk-subtasks. For that the decision parameter should be active. An example: If a task group with a pre-defined time of 15 s contains walk tasks with 3 s simulation time, then all tasks of this task group except the walk tasks are scaled to 12 s. This implies the duration of the walk subtask is not changed/scaled and thus the total duration of the task group remains the same (15 s).
The Restore default settings button allows you to reset the options in the Simulation tab to the default values.
