Transient convergence issue

[rh142]

I am running a transient dynamic analysis in ansys, at some time point it is failing to converge and the MAX DOF INC bounces back and forth between two point. I am including a sample. It bisects soon and converges but the same bouncing happens again and again. Eventually it reaches the limit and does not bisect again. I know that there is way to view residual forces in ANSYS I just can't seem to remember or find the command in help. Any help is appreciated.

Thanks

EQUIL ITER 6 COMPLETED. NEW TRIANG MATRIX. MAX DOF INC= -0.1623E-05
FORCE CONVERGENCE VALUE = 1922. CRITERION= 10.85
MOMENT CONVERGENCE VALUE = 0.2778E-06 CRITERION= 0.3117E-02 <<< CONVERGED
EQUIL ITER 7 COMPLETED. NEW TRIANG MATRIX. MAX DOF INC= 0.1623E-05
FORCE CONVERGENCE VALUE = 1.004 CRITERION= 0.2982E-01
MOMENT CONVERGENCE VALUE = 0.3128E-06 CRITERION= 0.3207E-02 <<< CONVERGED
EQUIL ITER 8 COMPLETED. NEW TRIANG MATRIX. MAX DOF INC= -0.1623E-05

Look up the help for the nldiag command. I believe what you want is:

nldiag,nrre,X

Where X is the number of Newton Raphson residuals you wish to store.

Hope this helps,
