Analyzing Validation Results

This section of the tutorial covers the analysis of the validation results.

The following scene shows the solution after 400 time-steps, plotted in the temperature range of 300 K to 400 K.

Open the Door Temperature plot which shows comparison at the defined line-probe location.

The temperature profile from the simulation is in good agreement with the profile based on experimental data.
Open the Door Velocity plot which shows comparison at the defined line-probe.

The simulated velocity profile shows good agreement with the experimental data up to a height of 1.5 m. After this point, the experimental data indicates that the maximum velocity in the boundary layer is higher than the simulation predicts. One cause for this difference could be an insufficient density of cells in the upper region of the doorway. Good simulation practice would be to reduce the volume mesh Base Size to 0.05 m, remesh the domain, and rerun the simulation using the finer mesh. Using a finer mesh size gives closer agreement between the simulated and experimental results.
