DIMPES
Recognised by the OPM Flow parserSCHEDULE
This keyword, DIMPES, defines the Implicit in Pressure Explicit Saturation (“IMPES”) dynamic solution parameters and results in the simulator switching from the current solution formulation to the IMPES formulation. OPM Flow uses a different numerical scheme which makes this keyword redundant; hence, OPM Flow ignores this keyword. It is documented here for completeness.
There is no data required for this keyword.
See section 2.2Running OPM Flow 2023-04 From The Command Lineon how to invoke various numerical schemes via the OPM Flow command line interface.

-- ACTIVATE THE IMPES SOLUTION OPTION
--
DIMPES
The above example switches on the IMPES solution option; however, this has no effect in OPM Flow input decks.Manual source: parts/chapters/subsections/12.3/DIMPES.fodt
