Adaptive Step Selection for a Filtered Implicit Method

Published 1 Apr 2025 in math.NA and cs.NA | (2504.00405v1)

Abstract: Pre-filtering and post-filtering steps can be added to many of the traditional numerical methods to generate new, higher order methods with strong stability properties. Presented in this paper are a variable step pre-filter and post-filter that allow adaptive time stepping for a filtered method based on Implicit Euler.
