Next, there is information about the topological operations in the
TOPO section. For each subdomain, this section reports
the number of elements, faces, segments, and nodes, as well as the spatial
dimension. For each boundary set and each intersection between subdomains, it
reports the number of faces, segments, and nodes, and the dimension.

The FIELDS section has information about the fields used
by Ansys Polyflow. Some fields (for example, coordinates or velocity) are directly defined
by sub-tasks, while others (for example, normal/tangential field) are required for
boundary conditions or other constraints. For all fields, the listing successively
reports the domain of definition (support), the interpolation type, the tensorial
type (scalar, vector, or tensor), the number of components, and the number of
variables.
For the interpolation type, P1;C0 indicates a linear
continuous interpolation, P2;C0 a quadratic continuous
interpolation, and so on.

contains a list of the problems being solved, as well as information about the
solution methods, mesh decomposition and optimization, memory usage, iteration
count, and convergence.
Solver information can be somewhat complex; however, it is a good idea to check the range of pivots as well as the RP growth factor (or reciprocal pivot growth factor). The range of pivots can be large, especially for complex cases, and 10 orders of magnitude between the minimum and maximum pivots are not unusual. The RP growth factor is an indication of the quality of the factorization. A large range of pivots in combination with a very low value of the RP growth factor, may suggest possible difficulties.
Subsequent to the linear algebra related information mentioned above, the section also displays information about convergence or divergence for the fields involved in the calculation.
This information is displayed in a table:
The first column is related to the field name and its influence on the convergence and the precision of transient problems. The field influence on the convergence and the precision, can be: "CP", "C", "Un" or "NI".
"CP" (Convergence and Precision): the corresponding field is used for the evaluation of the convergence of the solver as well as for the precision in transient calculations.
"C" (Convergence): the corresponding field is considered for the global evaluation of the convergence of the solver, but is not used for the evaluation of the precision in transient calculations.
"Un" (User n): the corresponding field undergoes a user-specific convergence criterion; it is considered for the global evaluation of the convergence of the solver, as well as for the evaluation of the precision in transient convergent calculations. In this case, you can ask for a convergence criterion of
, where ε is the convergence criterion of
the solver. "NI" (No Influence): the corresponding field is not considered for the global evaluation of the convergence of the solver, nor is it considered for the evaluation of the precision in transient calculations.
The second column provides the relative variations of the field and its convergence status. For the main solver, the status "OK" is provided for individual fields once it is verified that they have met the selected convergence criterion. For the "NI" field, the label "OK" will not appear.
The third column is related to the right hand side reduction and its trend. Usually, at convergence, the right hand side reduction should be of the same order of magnitude than the relative variation and lower than the convergence criteria. The trend of the right hand side reduction can be "- -", "-", "+", "++".
"- -" means the right hand side has been reduced by a factor greater than 10.
"-" means the right hand side has been reduced by a factor lower than 10.
"++" means the right hand side has been increased by a factor greater than 10.
"+" means the right hand side has been increased by a factor lower than 10.
The fourth column provides the values of the current right hand side.
In this table, the symbol ".." means that the relative data is not relevant or not available.
When the solver requires only a single iteration, the right hand side data are not printed.
The detection of the convergence depends upon the relative change of the fields. The data related to the right hand sides are given for information only; there are not taken into account for the convergence detection.
Note: The contents and layout of this section may vary according to the specific linear solver used in the simulation.
