it means your system is singular .. unless you goofed in your material definitions and node numbering, add more boundary conditions

your solver is failing. if it is occuring during the analysis your problem is ging nonlinear and you have a 0 stifness, if at the start your model is incorrect due to incorrect material args or boundary conditions.
