    Hi,

     

    To output mass and CoG, please add MASSPROP. Go to Control cards>> OUTPUT>> MASSPROP>>ALL

     

    Epsilon value gives you an idea how stable is the numerical problem is. As long as the value is small (in order of 1e-8), the problem is stable. If this is more then there is something wrong with the problem.
