The 6356 6356 precursor run is allowed to have a smaller domain along x and y 6357 6357 compared with the main run. Also, different numbers of processors can 6358 6358 be used for these two runs. Limitations are that the precursor run must 6359 use cyclic horizontal boundary conditions and that the subdomains of 6360 the main run must not be larger than the subdomains of the precursor 6361 run. If the total domain of the main run is larger than that of the precursor 6359 use cyclic horizontal boundary conditions and that the number of vertical grid points, <a href="#nz">nz</a>, must be same for the precursor run and the main run. If the total domain of the main run is larger than that of the precursor 6362 6360 run, the domain is filled by cyclic repetition of the (cyclic) 6363 6361 precursor data.
