 3d-data from a precursor run are read by the initial (main) run. The
 precursor run is allowed to have a smaller domain along x and y
 compared with the main run. Also, different numbers of processors can
 be used for these two runs. Limitations are that the precursor run must

 run, the domain is filled by cyclic repetition&nbsp;of the (cyclic)
 precursor data. This initialization method is recommended if a
