Fields exhibiting skew symmetry occur frequently in structural problems. There are many situations where non‐skew‐symmetric functions are conveniently used to analyse these skew fields. Specification of force and displacement conditions on the skew axis reduces the analysis to a half of the domain. The difficulty in using such conditions in an FEM analysis is their non‐explicit nature. A method of overcoming this difficulty is developed using concept of generalized forces and displacements.
