Six small circles on the component indicate the type of fixation: The first three correspond to translations in global x, y and z-direction, the last stand for rotations about the global x, y and z-axis. Filled circles indicate fixation which means that the corresponding degree of freedom is zero. The state of each circle can be changed by clicking on it. The string output of the component lists node-index or nodal coordinate, an array of six binaries corresponding to its six degrees of freedom and the number of load-case to which it applies. Supports apply to all load cases by default.
