Detailed Description

Perform Fourier-on-fly transformation.

Forier-on-fly is performed at nodes having nonzero bufer size bufsize. Node which records binary file at the end of the simulation is defined by SetRecordingFileNode.

StartRecord()

virtual int emFourierRecorder::StartRecord ( int  it )

virtual

Parameters

it	iteration from which recording is started (not zero if record is continuing after restarting the numerical experiment, it<0 means refreshing old file).

Implements FieldsRecorder.
