MW
Recognised by the OPM Flow parserPROPS
The MW keyword defines the molecular weights for each of the compositional components active in the model and for each equation of state. The keyword should only be used if the compositional mode has been requested using the COMPS keyword in the RUNSPEC section.
OPM Flow does not currently support the general compositional modeling formulation.
This keyword is not supported by OPM Flow but it will be parsed and its data ignored.
Notes:
The keyword is followed by NMEOSR records as specified by the TABDIMS keyword in the RUNSPEC section.
Each record must contain COMPS values as specified by the COMPS keyword in the RUNSPEC section.
Each record is terminated by a “/” and there is no “/” terminator for the keyword.
- Records
- Fixed number of records
- Variadic
- The record accepts a variable number of items
