Discretization Error Definition
5:21 am First, you are not following the netiquette. You might want to review it under Rules discretization error in fea on the xansys.org website before you post again. When I go to the Ansys Help feature and do a search on SERR, the second hit is "19.7 Post1 -

The stresses are calculated at certain points within each element. These points are strategically located within an element to provide accurate results. They are called Gaussian or quadrature points. After calculating the stresses at the Gaussian points, the program calculates the nodal stresses for each element by extrapolation. For an exact solution, all elements should give identical stress values at their common nodes. While the displacement field obtained by FEA is continuous, the stress field is usually discontinuous from one element to another. Different elements give stress values that are generally different at a common node. The program calculates the nodal stresses at a common node by averaging the values given by the contributing elements. The variation in stresses at common nodes provides a measure for the accuracy of the solution based on strain energy principles. The software estimates the error distribution as follows
