Extended statistics: sampling of skewness and kurtosis
Hello,
I would like to sample the skewness and kurtosis of the velocity field. In other words one could easily access the first and second order moments (uMean and uPrimeToMean) and now I would like to extend this to access also the third and forth order moments. My first guess would be to include the sampling of mean(u_i*u_j*u_k) in fieldAverage.C. Now my questions are: 1) Is there already something included in OpenFoam and I am to stupid to find it? I know that third and fourth order moments are not quite common in fluid mechanics. 2) Did anybody already implemented something like skewness and tested it successfully? May I could have a look into the code :rolleyes: kind regards, Fabian |
Nobody has an idea?
