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
