HYSTERESIS(1)

NAME
hysteresis - Tool to extract relative permeability and capillary pressure curves with hysteresis if enabled

SYNOPSIS
hysteresis DATA_FILE SATURATION_FILE OUTPUT_FILE TWOPHASE_SYSTEM [CELL_INDEX]

DESCRIPTION
Extracts the relative permeambility curves and capillary pressure curves with hysteresis if enabled for a cell in the model and writes them as tables to a CSV file.

DATAFILE, Data file name that contains keywords SGOF, EHYSTR etc.

SATURATION_FILE, a file that contains the requested saturations. It should contain one saturation value per line. Whether this is the gas or water saturation depends on the parameter TWOPHASE_SYSTEM. It will be the saturation of the first mentioned phase of the specified system.

OUTPUT_FILE, the name of the CSV file that we write the relative permeability and capillary pressures curves to. There will be one line for each saturation value from SATURATION_FILE. Each line will contain the values [sw, krw, kro, pcow, krnSwMdc(So at turning point), Sn(trapped s) ]. (Or equivalent for GO or GW systems.)

TWOPHASE_SYSTEM, The two phase system to use for outputting the first two phases. Should be one of the following strings: WO (for water-oil, water first, then oil), GO (for gas-oil), or GW (for gas-water)

CELL_INDEX: cell index (default is 0), to be used to determine SATNUM/IMBNUM value that is used for the calculation
