Abstract
The problem of generation of surplus displacement variables in general purpose finite element codes, using the displacement method, is discussed. A method of automatic selection of independent variables is proposed which eliminates abortive computer runs from this source and saves engineer data preparation. Extensions of the algorithm are outlined and the uniqueness of solution demonstrated by an example.
