Detailed Description

Compute second moments for two variables

Computes second-moment statistics for any two variables. For example, if the velocity field is provided, then it computes the following quantities:

\(\langle u'u'\rangle, \langle u'v'\rangle, \langle u'w'\rangle, \ldots\)

Alternately, using velocity (vector) and a scalar (e.g., temperature \(\theta\)), would compute:

\(\langle u'\theta ' \rangle, \langle v' \theta ' \rangle, \langle w' \theta ' \rangle\)
