To run FieldConvert in parallel the user needs to compile Nektar++ with MPI support and can employ the following command
<nprocs> with the number of processors. This will produce multiple
.dat files of the
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.
