What numerical algorithm is used by the Flownex Designer when solving design problems? The convergence behavior can appear similar to a Newton-Raphson process, and users may want to understand the underlying method in order to accurately describe how the Designer reaches a solution.
The Flownex Designer uses the Newton-Raphson solution algorithm to solve the set of equations associated with the design problem. During the solution process, the algorithm iteratively updates the design variables and evaluates the residuals until the specified convergence criteria are satisfied.
Because the Designer's convergence behavior is based on the Newton-Raphson method, users may observe successive iterations that progressively reduce the solution error and move the design variables toward the converged solution.
