MAP-online offers online use of the models distributed on MAP (Materials Algorithm Project). A large variety of models will be, in time, made available, from empirical models of mechanical propoerties of various alloys, to diffusion calculation in multicomponent systems.
The source code for all the models available online can be found on MAP. However experience shows that most of the time, users who could otherwise benefit from the use of these models are put off by the compilation process or the need to work with command-line programs.
