FEMtools™ SDM
Real-time Simulation of Structural Dynamics Modification

Structural Dynamics Modification (SDM) is a design-oriented tool to rapidly simulate effects of structural changes on the dynamics of structures. A library of lumped, 1D, 2D or 3D modification elements is available to model most commonly encountered structural modifications. Because only a model geometry and modal parameters are used, SDM works on finite element data, test data and hybrid models. The structural changes can be modeled as simple springs, masses, dampers, or any type of finite element (bar, beam, shell, volume).
