Efficient simulation of unsaturated flow in heterogeneous soils using an exponential integrator
Carr, Elliot (2009) Efficient simulation of unsaturated flow in heterogeneous soils using an exponential integrator. In QANZIAM Meeting 2009, 24-25 October 2009, Boonah, Qld. (Unpublished)
Provided a practical variable-stepsize implementation of the exponential Euler method (EEM).
Introduced a new second-order variant of the scheme that enables the local error to be estimated at the cost of a single additional function evaluation.
New EEM implementation outperformed sophisticated implementations of the backward differentiation formulae (BDF) of order 2 and was competitive with BDF of order 5 for moderate to high tolerances.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
