Detailed Description

This class records fields to the binary file.

After calculation this binary file can be used to plot fields history.

Member Function Documentation

SetTextHeader()

virtual int FileRecorder::SetTextHeader ( const std::string &  head_ )

inlineoverridevirtual

Set slice (frame) text header .

Supported by QPLT format. The information will be used while writing the next slice header.

Reimplemented from FieldsRecorder.

StartRecord()

int FileRecorder::StartRecord ( int  it )

overridevirtual

Start recording.

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.
