LSMPQS is a software package for
simulating capillarity controlled, immiscible fluid displacement
(drainage and imbibition) in porous media.

carbonate sample (approximately 600 microns on each side).

Non-wetting/wetting fluid contact is shown in red, NW phase/grain
contact is in gray, and snapped-off (trapped) blobs are in blue. For

or from segmented images of real rocks.

configurations obtained from LSMPQS simulation are detailed and
quantifying saturation, volumes, interfacial areas etc. is
straightforward. Having suitable geometry, you can obtain
capillary-pressure curves or study pore scale phenomena in a small
ensemble of pores.

Windows try Cygwin). C/C++

Many thanks to Steven L. Bryant for the continued encouragement, Elena
Rodriguez-Pin for helping to test the code, and Kevin Chu for
always being knowledgeable and helpful be it level sets or websites!
Since 2006, the code development has been, at various levels, supported
- Baker Atlas
- Departement of Energy, grant DE-FC26-06NT43067, "
Leading to Co-Existence of Gas and Hydrate in Ocean Sediments"
- Department of Agriculture, grant 2007-35102-18162,
the Mechanisms of Pathogen Retention In Unsaturated Soils"
but not the least...
Needless to say, this code is work in progress. Please email me
find the software useful, and have any type of feedback - this will
motivate future improvements.
Further, if you use the code in your work, I would
appreciate if you cite the paper
started it all
