Calculation settings apply only to the model being edited.

Contains the following elements:

• Maximum calculation step duration, days;
• Maximum non-linear iterations;
• Pressure calculation accuracy, atm;
• Inter-tank flow calculation method. From the drop-down list you can select Fully implicit scheme or Crank-Nicholson scheme;
• Linear equation solving method. From the drop-down list you can select GMRES method or Gauss method;
• Krylov subspace dimension;
• Maximum linear iterations;
• Linear equation solving accuracy;
• Maximum relaxation factor;
• Pressure change constraint;
• Minimum calculation step duration;
• Stop calculation if convergence issues arise;
• Tanks start operating at beginning of production/injection;
• Forecast calculation method – by wells or by tanks;
• Production/injection history – per period, cumulative, or daily rates.
• PVT modeling method – correlations or tables
