Abstract:  We have developed a structured adaptive mesh refinement (SAMR) method for parabolic systems. Solutions are calculated using the finite-difference or finite-volume method in space and backward differentiation formula (BDF) integration in time. The combination of SAMR in space and BDF in time is designed for problems where the fine-scale profile of sharp fronts in space should be resolved and implicit integration in time is necessary to improve the efficiency of the computation. Sensitivity analysis methods on the adaptive mesh are also presented.
