dynamis_2 is a numerical software leading to an automated determination of static and dynamic response of mechanical systems in a computationally efficient way. It is used for systems of critical importance and safety, like for predicting the behavior of automotive, aerospace, marine and civil engineering structures. These systems are discretized by finite elements. Frequently, this leads to models with an excessive number of degrees of freedom and strongly nonlinear characteristics. Therefore, a central concept of the code is to provide the option of reducing drastically the order of a system, without sacrificing numerical accuracy. Apart from increasing the computational efficiency and speed, this reduction renders amenable the application of techniques, which are efficient for low order systems only.

Multi Level Dynamic Substructuring

Besides the classical coordinate reduction approaches of Structural Dynamics, a new class of coordinate reduction methods has also been implemented in dynamis_2. This method is known as Multi-Level Dynamic Substructuring (MLDS).

In classical coordinate reduction methods, the computation and storage of the transformation matrix required in the reduction process becomes excessive for large scale systems. For such systems, a special method is applied, based on a multi-level, mathematical substructuring, which is performed within each structural component in an automatic way.
