 FORMING STIFFNESS AT ZERO (UNSTRESSED) INITIAL CONDITIONS

 TOTAL NUMBER OF EQUILIBRIUM EQUATIONS     =        2202
 NUMBER OF NON-ZERO STIFFNESS TERMS        =       55551

 * * * W A R N I N G * * *
 THE STRUCTURE IS UNSTABLE OR ILL-CONDITIONED !!
 CHECK THE STRUCTURE CAREFULLY FOR:
 - INADEQUATE SUPPORT CONDITIONS, OR
 - ONE OR MORE INTERNAL MECHANISMS, OR
 - ZERO OR NEGATIVE STIFFNESS PROPERTIES, OR
 - EXTREMELY LARGE STIFFNESS PROPERTIES, OR
 - BUCKLING DUE TO P-DELTA OR GEOMETRIC NONLINEARITY, OR
 - A FREQUENCY SHIFT (IF ANY) ONTO A NATURAL FREQUENCY

 TO OBTAIN FURTHER INFORMATION:
 - USE THE STANDARD SOLVER, OR
 - RUN AN EIGEN ANALYSIS USING AUTO FREQUENCY SHIFTING (WITH
   ADDITIONAL MASS IF NEEDED) AND INVESTIGATE THE MODE SHAPES


 NUMBER OF EIGENVALUES BELOW SHIFT         =           1
