The idea of OOFEMlib is to provide to the FEM analyst highly modular, easily extensible and robust enviroment. It can be also thought as an general FEM kernel of general FE program.
Here is a list of highlights:
-
object oriented architecture
-
modular and extensible FEM kernel (OOFEMlib) fully extensible - The kernel is extensible in any "direction". The possibility of adding new element type, new material model with any type and number of internal history parameters, new boundary condition, new numerical algorithm or new analysis module is matter of course.
-
independent problem formulation, numerical solution and data storage - The kernel provides the independent abstractions for analysis, general numerical method and data storage (sparse matrices). The component mapping concept allows to formulate problem and numerical method independently and allows to use any suitable numerical method for problem solution without changes. This concept is further enhanced by abstract sparse matrix interface, allowing to formulate numerical method independently on sparse matrix implementation.
-
full restart support - The kernel supports full restart from any previously saved state.
-
support for parallel processing (message passing) - General classes for efficient inter domain communication are provided built over the abstract general layer for message passing libraries, which is available on many parallel platforms (massively parallel computers, shared memory systems and workstation clusters) .
-
adaptive analysis support - multiple domain concept, fast spatial localization algorithms based on tree techniques are available.
-
includes enhanced support for structural analysis.
