Reduction from M parts to 1 part in serial for phasta files initially partitioned with NSpre_parallel
- cd to the procs_case directory that contains the files you want to reduce
- Run the executable:
~mrasquin/develop/phasta/phPost/phPost/bin/x86_64_linux-icc/reduce-openmpi-O -sn
where sn is the time step number. For example, the restart files corresponding to time step 5 would be restart.5.* and geombc.dat.* .
- The reduce operation will generate restart.##.0 in the procs_case directory, where ## stands for the step number you have reduced.
- restart.##.0, combined with geombc.dat.1 (which contains the boundary conditions for all the parts - it is created when you run NSPre_Parasolid), are what you need to see the solution on 1 part.
