Basically singularities are of two types, single grid based (Grid point singularity) & Multiple grids based (Mechanism type of singularity).

Grid Point singularity table will give you the grid ID's having singularity problem in the stiffness matrix. Some of the singularity problems can be solved by bulk data entry "PARAM AUTOSPC YES".
