 +After a successful simulation, SPACAR Light returns the compliance matrix of each node (per loadstep) - see the [[full_syntax|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). The stiffness matrix ''K'', for which ''f = K*u'', is the inverse of the compliance matrix ''C''.
