TOLCRIT
Recognised by the OPM Flow parserPROPS
Critical fluid saturations are determined from the relative permeability tables, that is the last saturation in a relative permeability table where the relative permeability of a phase is set equal to zero. Since floating-point numbers (as implemented in computers) are never exact, one cannot compare floating point numbers for exact equality. Thus, this keyword defines a value below which is considered equivalent to zero in determining the critical saturation for a phase.
Notes:
The keyword is terminated by a “/”.
See also section 8.2.4Saturation Tables (Relative Permeability and Capillary Pressure Tables)for a description of the relative permeability tables and the various end-point definitions, including oil, water and gas critical saturations.

| 1 | VALUEmanual: TOLCRIT | TOLCRIT is a real positive number greater than zero and less than one that defines the critical saturation tolerance used to determine the critical saturation of a fluid in the relative permeability tables. The default value of 1 x 10-6 means that relative permeabilty values less than this value will be treated as being equal to zero. | DOUBLE | 1 | dimensionless | dimensionless | dimensionless | 1 x 10-6 |
