Description: 
INSANE Interactive Structural Analysis Environment. An objectoriented tridimensional selfregular boundary element method implementation. The objectoriented design used to implement a selfregular formulation of the boundary element method is presented. The selfregular formulation is implemented to four integral equations: the displacement boundary integral equation, and the Somigliana’s integral identities for displacement, stress and strain. The boundarylayer effect that arises in the classical BEM on the transition from interior to boundary points is eliminated and thus special integration schemes to treat nearly singular integrals become unnecessary. The selfregular formulations lead to very accurate results. Comparisons of displacements, stress and strain obtained from analytical solutions and the numerical results for bidimensional and tridimensional elastostatics problems are presented, and the selfregular formulation shows strong stability. The implemented code is opensource and is available under the GNU General Public License
