## 4.4. Residual Plotting for ANSYS Multi-field Runs

The CFX-Solver Manager can be used to launch an ANSYS Multi-field Run. For such a run, it is not sufficient to consider only the convergence of CFX-Solver when deciding if results are converged: in addition, the convergence of CFX-Solver and the convergence of the data exchanged between the CFX and ANSYS Solvers must also be considered. The CFX-Solver Manager shows extra plots when monitoring an ANSYS Multi-field run to enable a graphical display of these extra convergence quantities.

For details, refer to the following sections:

- Coupling CFX to an External Solver: ANSYS Multi-field Simulations in the CFX-Solver Modeling Guide

- ANSYS Field Solver Plots

- ANSYS Interface Loads Plots

For the extra plots to be displayed, the CFX-Solver Manager must have started CFX-Solver by selecting an MFX Run Mode of either `Start ANSYS and CFX` or `Start ANSYS only` (see MultiField Tab), or CFX-Solver must have been started from the command line with the `cfx5solve` command. It is not possible for CFX-Solver Manager to display these plots if CFX-Solver was started by the ANSYS CFX Launcher or from the command line directly.
