A three-point sixth-order nonuniform combined compact difference scheme. (English) Zbl 0930.65116
The authors propose a three-point nonuniform combined compact difference (NCCD) scheme with sixth-order approximation for numerical solution of second-order differential equations. The accuracy and computational time advantages of the NCCD scheme model in comparison with the combined compact difference scheme is demonstrated on the example of the Stormmel ocean model.
