13.4 FieldConvert in parallel

To run FieldConvert in parallel the user needs to compile Nektar++ with MPI support and can employ the following command

mpirun -np <nprocs> FieldConvert test.xml test.fld test.dat

replacing <nprocs> with the number of processors. This will produce multiple .dat files of the form test_P0.dat, test_P1.dat, test_P2.dat. Similarly the VTK files can be processed in this manner as can the vorticity option. In the case of the vorticity option a directory called test_vort.fld (or the specified output name) will be produced with the standard parallel field files placed within the directory.
