Amethod is presented to significantly improve the convergence behavior of batch nonpremixed counterflow flame simulationswith\nfinite-rate chemistry.Themethod is applicable to simulations with varying pressure or strain rate, as it is, for example, necessary for\nthe creation of flamelet tables or the computation of the extinction point. The improvement is achieved by estimating the solution\nbeforehand. The underlying scaling rules are derived from theory, literature, and empirical observations. The estimate is used as\nan initialization for the actual solver. This enhancement leads to a significantly improved robustness and acceleration of batch\nsimulations.The extinction point can be simulated without cumbersome code extensions.The method is demonstrated on two test\ncases and the impact is discussed.
