## Chapter 4: Residual Plotting

CFX-Solver calculates solutions to various equations. However, many cases result in residual values. This is due to an equation not being fully satisfied. Of course, if the solution is exact, then the residual is zero. However, because equation results only approximate physics, the results in a solution do not always match reality.

This chapter describes:

- Equation Residual
- Convergence Results and RMS
- Transient Residual Plotting
- Residual Plotting for ANSYS Multi-field Runs
