Many of the differential equations cannot be solved except very special case. Therefore, it is necessary to get the solutions by the numerical analysis. It is an approximate method, and therefore, it includes errors. It is important to minimize the errors to meet the objectives of the analysis purposes. TS Consulting sometimes analyze the problems by this technology. The page explains the difference method, which is one of the numerical analysis. The 3D conversion of the outcome is also introduced for quick view of the calculated results.
