WIP: Post-processing calculation of TKE statistics
The current Reynolds Stresses filter in the IncNavierStokesSolver computes RS in run-time, using the accumulating velocity mean. An alternative approach consists of computing the the time-mean of the product of instantaneous velocity components in runtime, and then using these to compute the Reynolds Stresses: <u_i' u_j'> = <u_i u_j> - <U_i U_j>. With this approach, it is then also possible to calculate turbulent production and dissipation. The feature is divided in:
- TKEBalance filter (part of the IncNavierStokesSolver) to compute the necessary quantities in runtime
- TKEBalance FieldConvert module to compute RS, turbulent production and dissipation, that replace unnecessary variables in the final output file.
