People


Here are the people that have worked on Geocrack2D and Geocrack3D.

Geocrack3D (present to past)

hardeman.jpg (8341 bytes)Brian Hardeman (Assistant Scientist) is responsible for the topological data base and overall Geocrack3D design, particularly the user interface.

kulkarni and swenson.jpg (44094 bytes)Sarang Kulkarni (right) and Daniel Swenson.  Kulkarni is implementing the object-oriented finite element solution in C++.  Swenson has written a small part of the 3D code, but mainly tries to keep up.  This picture shows the blue New Mexico sky at the Rio Grande Gorge Bridge near Taos.  At 650 feet above the river, this is the second highest bridge in the United States.

liu.jpg (16024 bytes)Tan Liu will be continuing Kulkarni's work, adding heat transfer and elastic solution. Here he is in New Mexico in front of a bed and breakfast that he visited with his fiancee.

Mark James (see picture below) helped us during design of the finite element program and with general ideas during the entire development.

hardeman and duteaux.jpg (38581 bytes)Bob DuTeaux (left) and Brian Hardeman.  Bob worked at Los Alamos, helping to run tests and used Geocrack2D for analysis.  Brian added tracers, got everything under source control, and did a lot of miscellaneous maintenance.  This picture was taken at the Fenton Hill site, during operation.

sprecker.jpg (9587 bytes)Tim Sprecker added heat transfer.  He was also the first person to make the whole code work, spending a lot of time checking every menu, etc.

Mel Beikmann finished the coupling of the fluid flow and structure solution.  This allowed us to reliably obtain converged solutions.

Rick Martineau moved the code to the Sun workstations, including the graphics display.

Shun-Lung Su solved the fluid flow problem.
