[en] The program is applicable to linear problems and has been developed as the foundation of a nonlinear finite-element program for the analysis of two- and three-dimensional structures. It was developed as part of an investigation of prestressed concrete reactor vessels. Hence it is oriented towards the analysis of reinforced and prestressed concrete structures. The operational part of the program can be used to obtain elastic stress and strain distributions in a two-dimensional continuum; namely plane stress, plane strain and axisymmetric stress conditions
