NEWTON

Recognised by the OPM Flow parserSUMMARY

Part of the PERFORMANCE_PROBE keyword family in the OPM Flow parser.

This keyword activates the writing out of the Newton iteration vector (the number of non-linear iterations per time step) to the SUMMARY file, and the RSM file if the RSM file option has been requested by the RUNSUM keyword in the SUMMARY section,

There is no data required for this keyword and there is no terminating “/” for this keyword.

Although the keyword is recognized by OPM Flow only zeros are written to the SUMMARY file.

The above example activates the writing out of the Newton iteration vector to the SUMMARY file.
