-After a successful simulation, SPACAR Light returns the compliance matrix of each node (per loadstep) - see the Full Syntax List. For a compliance matrix ''​C'',​ it holds that ''​u = C*f''​. Vector ''​u = [ux;​uy;​uz;​rx;​ry;​rz]''​ consists of displacement components ''​ux'',​ ''​uy'',​ ''​uz''​ (in the ''​x''​-,''​y''​- and ''​z''​-direction,​ resp.) and rotation components ''​rx'',​ ''​ry'',​ ''​rz''​ (about the ''​x''​-,''​y''​- and ''​z''​-axis,​ resp.). Vector ''​f = [fx;​fy;​fz;​mx;​my;​mz]''​ consists of force components ''​fx'',​ ''​fy'',​ ''​fz''​ (in the ''​x''​-,''​y''​- and ''​z''​-direction,​ resp.) and moment components ''​mx'',​ ''​my'',​ ''​mz''​ (about the ''​x''​-,''​y''​- and ''​z''​-axis,​ resp.). For the '​global'​ compliance matrix ''​CMglob'',​ the components are resolved in the global coordinate frame. This is the fixed (inertial) frame (which is also the axes frame indicated in SpaVisual with labels ''​x'',​ ''​y''​ and ''​z''​). For the '​local'​ compliance matrix ''​CMloc'',​ the components are resolved in the local frame of the node (meaning that the coordinate frame rotates with the node).+After a successful simulation, SPACAR Light returns the compliance matrix of each node (per loadstep) - see the [[full_syntax|Full Syntax List]].
