Iteration monitor list for pipeline analysis with nonlinear soil and geometrically nonlinear pipe behaviour (Output Table)
Data description/Result options:
ITER:
Iteration sequence number (n)
REMARK:
Type of iteration in case of nonlinear calculations
Infinite Bend Angle: 

Limited Bend Angle

No effect of ovalisation on stiffness taken into account 
Ovalising 
Effect of ovalisation on axial stiffness taken into account 
Material Nonlinear 
Material nonlinearity taken into account 
Nonoval./Oval. 

Oval./Mat. Nonlin. 

Nonoval./Mat. Nonlin. 
NLERFLDS:
Number of soil lateral reaction error fields after soil iter (n)
NFERFLDS:
Number of soil axial friction error fields after soil iteration(n)
NTERFLDS:
Number of soil torsional friction error fields after soil iter (n)
NERFLDS:
Summated number of soil iteration error fields
(NERFLDS = NLERFLDS + NFERFLDS + NTERFLDS)
MFERPTS:
Max. no. of soil iteration error points occurring in 1 error field
NERPTS:
Total number of soil iteration error points contained in RERFLDS including error points at boundary nodes
DISEQ:
Disequilibrium indicator
(The disequilibrium indicator is the lower (truncated) integer ratio of:
The norm of the disequilibrium force vector divided by the norm of the total external+internal force vector and the specified RELDISEQ or ABSDISEQ value.
DISEQ = 9999 for all values ≥ 9999
DISEQ = 0 means 'NEAR STABILITY'
DISEQ = 'blank' means 'STABILITY' (see also the table description))
DISPMAX:
Calculated overall maximum translation
DISPADD:
Calculated maximum additional translation
(The DISPADD value is the maximum translation displacement found in this iteration due to 100% of the disequilibrium load. The additional translation does not necessarily add to DISPMAX.)
IT.FACTOR:
Multiplication factor on the disequilibrium load used in this iteration. Effective addition to displacements is DISPADD*IT.FACTOR
The number of rows is the number of iterations required to meet SOILCTL and GEOMCTL criteria.
