The number of the free variables can be fairly large. Most numerical solvers used to determine free variables of dynamical systems rely on first-order derivatives of the state of the system w.r.t.

In spite of reasonable restrictions, the language is rich enough to express and differentiate any cumbersome equation with practically no effort. Among other things, the language syntax supports functions, compile-time ranged for loops, if/else branching constructions, real variables and arrays, and allows for manually discarding calculations where the automatic derivative values are expected to be negligibly small.

The Turing incompleteness allows for a sophisticated source code analysis and, as a result, a highly optimized compiled code. Landau is a Turing incomplete statically typed domain-specific language aimed to fill this gap. Even though there exist many automatic differentiation tools, none has been found to be scalable and usable for practical purposes of modeling dynamical systems. One of the approaches to obtaining these derivatives is the integration of the derivatives simultaneously with the dynamical equations, which is best done with automatic differentiation techniques. The number of free variables can be fairly large. Most numerical solvers used to determine the free variables of dynamical systems rely on firstorder derivatives of the state of the system with respect to the free variables.

The present time integrator has been proven to produce more accurate numerical results than the MATLAB solvers, ode45 and ode15s. Two examples of the Burgers equation in one and two dimensions have been solved via the ChCM-IELDTM hybridization, and the produced results are compared with the literature. The produced method is shown to eliminate the accuracy disadvantage of the classical \theta-method and the stability disadvantages of the existing DTM-based methods. With the help of the global error analysis, adaptivity equations are derived to minimize the computational costs of the algorithms. A robust stability analysis and global error analysis of the IELDTM are presented with respect to the direction parameter \theta. For spatial discretization of the model equation, the Chebyshev spectral collocation method (ChCM) is utilized. The IELDTM is adaptively constructed as stability preserved and high order time integrator for spatially discretized Burgers equation. The adaptive IELDTM has been proven to integrate the stiff Chapman ADR equations with optimum costs over relatively long-time intervals.Ī new implicit-explicit local differential transform method (IELDTM) is derived here for time integration of the nonlinear advection-diffusion processes represented by (2+1)-dimensional Burgers equation.

The IELDTM is extensively compared with the widely used MATLAB solvers, ode45 and ode15s. The present time integrator is proven to provide more efficient numerical characteristics than the various multi-step and multi-stage time integration methods. Two examples of the Burgers equation in one and two space dimensions and the Chapman oxygen-ozone ADR model are solved via the ChCM-IELDTM hybridization. The produced method is shown to eliminate the accuracy disadvantage of the classical \(\theta \)-method and the stability disadvantages of the existing differential transform-based methods. A robust stability analysis and global error analysis of the IELDTM are presented with respect to the direction parameter \(\theta \). The IELDTM is adaptively constructed as a stability preserved and high order time integrator for spatially discretized ADR equations. A new implicit-explicit local differential transform method (IELDTM) is derived here for time integration of the nonlinear (2 + 1)-dimensional advection–diffusion-reaction (ADR) equations.
