LUGR

Adaptive-grid methods for time-dependent PDEs.

This project belongs to CWI's research program Mathematics & the Environment. It was terminated in 1994.

Project Description:

The LUGR project was carried out in cooperation with and partially sponsored by the Ground Laboratory of the RIVM - the Dutch National Institute of Public Health and Environmental Protection. The aim was to develop efficient solvers for the numerical simulation of brine flow for predicting the potential transport of radioactive pollutants.

LUGR methods are meant for the efficient computation of rapidly varying temporal and spatial solution transitions by automatic local grid adaptation (more). A typical solution, with the grids used, looks like:
