dear all i have solved a below attached problem in RADIOSS and obtained the results as i have attched in the PCH file..but the Sum of moments in X and Y directions is not matching with the SPCF moment results in the respective directions

i.e sum of applied moments in Y direction is -7.899E+04 but in PCH file SPC moment (reaction) in Y direction is 1.273286E+05 + -1.516917E+05 +  2.031026E+04 = -4053

i.e applied moment -78986 is not matching with reaction moment -4053

but as per equilibrium summation of moment in particular direction is not satisfying..

I am attaching all the files regarding this.. kindly anybody help me in this..

    I think the way you are calculating moment is not correct.
