nThe nodal displacement solution allows the post processor to compute the element stresses and strains. The element formulation includes a definition of the shape function, which defines what the strain is everywhere in the element, including the corner nodes. The gauss points are not very relevant during post processing.nGauss points are defined in the element formulation and can have an effect on the solution process and the resulting nodal displacements. You may have seen keyopts that can change how many gauss points are used in an element. That might be done to avoid problems that can occur in the solution such as hourglassing or volumetric locking.n
