Operator splitting method for numerical solution of modified equal width equation
İ. Çelikkaya
In this manuscript, numerical solutions of the equations in the form of $u_{t}=Au+B(u)$ have
been sought for, where $A$ and $B$ are linear and nonlinear operators, respectively.
The modified equal width (MEW) equation has been converted into two sub problems.
Then, the sub problems were solved according to the Strang splitting scheme by applying the cubic Bspline collocation
finite element method. Thus, more accurate results of the equation MEW have been obtained
than those nonsplitting users. In order to test the accuracy and efficiency of the present method;
single soliton, interaction of two solitons and Maxwellian initial condition pulse problems have
been considered. Moreover, the stability analysis of each sub problem has been investigated by
vonNeumann analysis method.
