Linear equation solving methods
NettetLinear equation solution is used in linear and nonlinear analysis. In nonlinear analysis Abaqus/Standard uses the Newton method or a variant of it, such as the Riks method, within which it is necessary to solve a set of linear equations at each iteration. The direct linear equation solver finds the exact solution to this system of linear equations (up …

To solve linear equations, find the value of the variable that makes the equation true. Use the inverse of the number that multiplies the variable, and multiply or divide both sides by it. Simplify the result to get the variable value. Check your answer by plugging it back into the equation.
NettetIterative solver basics. The iterative solver in Abaqus/Standard can be used to find the solution to a linear system of equations and can be invoked in a linear or nonlinear static, quasi-static, geostatic, pore fluid diffusion, or heat transfer analysis step. Since the technique is iterative, a converged solution to a given system of linear ...
