Coupled thermal flow convergence graphs
The Convergence window displays the following residual curves:
Surface temperature curve for elements that are in contact with the fluid. The maximum temperature changes are obtained from the thermal solver.
Imbalance heat curve for convected heat that is exchanged between the thermal and flow solvers.
Note:
To make the graphs readable when initial residuals may be very high, the solution monitor clips residual and temperature values sent to convergence graphs at a value of 20.
