Hi Silvia,
I normally use FieldConvert to reduce the number of files in a .fld folder before downloading flies from supercomputer,
mpirun -np <nprocs> FieldConvert test.xml test.fld reconstruct-test.fld.
To get a single *.fld file, <nprocs> = 1 should be used.
Hope it helps!
Kind regards,
Chengjiao

Subject: [Nektar-users] Restarting a simulation from last data

Dear all,
I understand Nektar has a restart capability which involves renaming the last .fld output file as a .rst file. Then, configure the FUNCTION 'InitialConditions' accordingly.
In case of large files, the .fld file is partitioned in files with names P0000000.fld, P0000001.fld, etc and the Info.xml file is generated.
How do we generate the start file from the parallel partition? I assume a single .fld file is needed for restarting a simulation.
Thank you for your help.
Kind regards,
Silvia
