Here is the meaning of terms.They are related to solver processing.
o A_DELNRM: The Accumulated Total Norm
o NJAC: The Total Number of Jacobian Evaluations
o NRES: The Total Number of Residual Evaluations
o ANRF: The Accumulated Total Number of Newton Raphson Failures (The Maximum
Iteration is 10 in RecurDyn.)
o AINF: The Accumulated Total Number of Integration Failures (During the
Newton-Rhapson Iterations, if the total norm of the current step is greater
than that of the previous step, RD counts this case as the number of
Integration Failure.)
