Virtually any machine made in the 90's will suffice. A continuing interest from research days at Leeds. Own practice programs include wave propagation along channels , wave propagation over an area and flood routing through a reservoir. Not a specialist interest but competent to design small structures and analyse larger ones. One of the lessons of Marine work in North Africa and the Middle East is the need for durable concrete and consequences of not taking sufficient precautions.
Geotechnical considerations feature largely in landfill development.
Applications have been written including a part complete slip circle program. Other programs include a project management suite , a driver for a Canon LBP4 laser printer and a fractal generator which can make bitmaps that a Canon LBP4 laser printer prints at full 300dpi resolution. Although written for the LBP4 the programs should work on the LBP8 MkIII as it shares a programming manual with the LBP4. I would be like to know whether they work on more recent Canon laser printers. Printing is on a Canon LBP4 laser printer.
