 The averaged mixing quality is calculated as the arithmetic mean of the mixing qualities of the two initial distributions. The averaged mixing quality is calculated as the arithmetic mean of the mixing qualities of the two initial distributions.

 +If the analysis includes particle tracking and thus an assessment of distributive mixing quality, a thermal mixing index is also calculated. This index can be regarded as an extension of the distributive mixing quality metric that incorporates the standard deviation of the temperature at the flow outlet. Both the standard deviation and the thermal mixing index can be found on the “Process Data” page. \\
 +Since the initial temperature distribution in the simulation is unknown, the simulation starts with a uniform inlet temperature. As short elements therefore also exhibit a homogeneous temperature distribution at the outlet, the calculation is coupled with the distributive mixing quality, which also plays an important role in achieving thermal homogeneity. The calculation is performed as follows:
 +
 +$$ MQ_{therm.} = \exp\left(-(1 - MQ)\,T_{\mathrm{stabw}}-\frac{2}{1+\exp\left(20(MQ-0.55)\right)}\right)$$
