The most commonly used Runge Kutta method to find the solution of a differential equation is the RK4 method, i.e., the fourth-order Runge … WebAug 27, 2024 · By "fourth order" I presume you mean rank 4, but that is with regard to the original vector space. A tensor is also a "Vector" in its own vector space as well as a linear operator in several settings but you seem to be implying a double contraction wherein you are mapping rank 2 tensors to rank 2 tensors.
WebJul 9, 2024 · A fourth-order compact finite difference scheme of the two-dimensional convection–diffusion equation is proposed to solve groundwater pollution problems. A suitable scheme is constructed to simulate the law of movement of pollutants in the medium, which is spatially fourth-order accurate and temporally second-order accurate. The … WebTaking 8×(first expansion − second expansion)−(third expansion − fourth expansion) cancels out the ∆x2 and ∆x3 terms; rearranging then yields a fourth-order centered difference approximation of f0(x). Approximations of higher derivatives f00(x),f000(x),f(4)(x) etc. can be obtained in a similar manner. For example, adding
