This merge request updates !487 (merged) where manual loops where exchanged with
WALBERLA_FOR_ALL_CELLS macros. Since the macros are implicitly parallelized when using OpenMP, function
setDomainCells() does not work as expected anymore. The content of vector domainCells will change when OpenMP parallelization is used such that its size can not be evaluated correctly in the later course of the algorithm. Thus OpenMP is turned off in the macro
This is the reason for the failure of the
ComplexGeometry benchmark on the current master (see job 672374).
