- the scotch interface still uses non-const pointers when passing in values. For the ConstPrecisionAdaptor this means that we need to cheat with a constCast(). Using ref() will rightly trigger complaints about trying to modify a const object.

- add a '-SPDP' option - remove the '-archOption' for forcing a '-m32' build on 64-bit architecture, which is now considered too obscure. Must edit files manually if this option is really required.

Kutalmış Berçin authored
The following three synthetic turbulence inflow boundary conditions are examined through single-cell-domain smooth-wall plane channel flow setup: - turbulentDFSEMInlet - turbulentDigitalFilterInlet variant=digitalFilter - turbulentDigitalFilterInlet variant=reducedDigitalFilter The examinations are performed in terms of the first-/second-order turbulence statistics provided by (Moser et al., (1999)) doi.org/10.1063/1.869966 from smooth-wall plane channel flow direct numerical simulations at Re=395. Serial executing: ./Allrun Parallel (decompositionMethod=scotch) executing: ./Allrunparallel

Velocity boundary condition generating synthetic turbulence-alike time-series for LES and DES turbulent flow computations. To this end, two synthetic turbulence generators can be chosen: - Digital-filter method-based generator (DFM) \verbatim Klein, M., Sadiki, A., and Janicka, J. A digital filter based generation of inflow data for spatially developing direct numerical or large eddy simulations, Journal of Computational Physics (2003) 186(2):652-665. doi:10.1016/S0021-9991(03)00090-1 \endverbatim - Forward-stepwise method-based generator (FSM) \verbatim Xie, Z.-T., and Castro, I. Efficient generation of inflow conditions for large eddy simulation of street-scale flows, Flow, Turbulence and Combustion (2008) 81(3):449-470 doi:10.1007/s10494-008-9151-5 \endverbatim In DFM or FSM, a random number set (mostly white noise), and a group of target statistics (mostly mean flow, Reynolds stress tensor profiles and length-scale sets) are fused into a new number set (stochastic time-series, yet consisting of the statistics) by a chain of mathematical operations whose characteristics are designated by the target statistics, so that the realised statistics of the new sets could match the target. Random number sets ---->-| | DFM or FSM ---> New stochastic time-series consisting | turbulence statistics Turbulence statistics ->-| The main difference between DFM and FSM is that the latter replaces the streamwise convolution summation in DFM by a simpler and a quantitatively justified equivalent procedure in order to reduce computational costs. Accordingly, the latter potentially brings resource advantages for computations involving relatively large length-scale sets and small time-steps.
