Emitter property page allows to specify parameters of monochromatic point emitter.
The Number of Trajectories: this field defines the total number of trajectories in the beam. The more trajectories you ask for, the longer will QuickField take to perform the calculation.
Source position: these fields define the coordinates of the point emitter. You can either enter the coordinates manually or click the required point inside the window showing the field.
Angle range: these fields define the limits for the angle between initial velocity vector and the horizontal axis. QuickField assumes that γ (the angle between initial velocity vector and the plane of the model) is the same for all particles in the beam.
Stop iteration when NNNN elements passed: the value entered into this field limits the number of finite elements the particle enters during its flight. This limitation helps to avoid infinite loops for closed trajectories.
Whenever you click the Apply button or click anywhere in the window showing the field, QuickField recalculates the trajectories and updates the picture. To preserve the previous trajectories click the left mouse button while pressing the CTRL key.
