Analysis software SFE AKUSMOD

acoustic simulationfor automotive applications

Study the interior acoustic of vehicles. Find out which parts of the structure contribute to noise emission and vibration. Evaluate and optimize lightweight structures with regard to comfort and acoustics. CATIA | SFE AKUSMOD puts you into a position to analyze and to improve interior acoustics/NVH in an early stage. Efficient mesh generation for NVH and interior acoustics Easy coupling of fluid-to-fluid and fluid-to-structure meshes Powerful post-processing with fast preview on NVH results Calculation and visualization of participation factors of individual structure panels or nodes in noise generation If interlinked with CATIA | SFE CONCEPT, additional factors can be included into the optimization process. Technology CATIA | SFE AKUSMOD is an integrated pre-/post-processor enabling detailed acoustic analysis and optimization of vehicle structures. CATIA | SFE AKUSMOD's smart cavity model builder identifies openings that can be patched automatically to saves pre-processing time. CATIA | SFE AKUSMOD uses weighting factors in its coupling that have proven to give reliable results. CATIA | SFE AKUSMOD Smart Coupling does not couple panels that are hidden by other panels. CATIA | SFE AKUSMOD's robust acoustic cavity and coupling generation and general batch capabilities give an advantage over it’s competitors. CATIA | SFE AKUSMOD Post-processing tools are fast, simple and efficient. They offer great potential to identify and fix noise problems. CATIA | SFE AKUSMOD can run in batch as part of an optimization loop - continuous and discrete variables are supported.
