FEMsimulointi

FEMsimulointi, known in English as Finite Element Simulation or Finite Element Analysis (FEA), is a computational method used to predict how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects. It is a powerful tool used by engineers and designers across various industries to optimize designs and avoid costly physical prototypes.

The core principle behind FEMsimulointi is to divide a complex object or system into a large number of smaller, simpler parts called finite elements. These elements are typically simple geometric shapes like triangles or quadrilaterals in 2D, or tetrahedrons or hexahedrons in 3D. Each element is then analyzed mathematically using predefined equations that describe its behavior under applied loads or conditions.

By connecting these elements at their nodes, the software can approximate the behavior of the entire structure. The more elements used, the finer the mesh, and the more accurate the simulation tends to be, though this also increases computational time and resources required.

FEMsimulointi allows for the prediction of stress, strain, temperature distribution, displacement, and other performance characteristics. This enables engineers to identify potential failure points, assess material strength, and refine designs for improved performance, safety, and efficiency before manufacturing begins. It is widely applied in fields such as aerospace, automotive, civil engineering, biomechanics, and electronics.
