This project have just started, thus many things are not setup yet.
Nadamak is a project to create a set of tools helping with research on computational mechanics. Nadamak is implemented in Matlab with some some infrastructure support in Python.
While documentation is being prepared one can look at demo pages.
Documentation is absolutely essential part of Nadamak, however making it is a huge effort. Despite the fact that Nadamak guide barely scratches the surface of the subject you can look at HTML version of it.
