The generated SPH elements (particles) are elements of mass configuration. Mass elements have a spherical graphical representation and also can have an element handle which places an additional label of the element's configuration with the graphical representation. In order to improve the visualization of SPH elements, Altair recommends turning off element handles. Element handles can easily be turned on/off from the Display toolbar using the Element Handles icon . SPH elements are created in the current component and are also colored the same as that component. The component color can be changed using standard Model browser functionality.
