ANSYS Acoustic Analysis as Understood by a Structural Analyst

December 18, 2018

10.30am - 12.00pm (IST)




Prediction of acoustic performance of products early in the design state and fine-tuning acoustic characters of the final marketable product is increasing important factor for the competitive edge. As the need increases, more and more Mechanical engineers are engaging in Acoustic simulations. By utilizing ANSYS acoustics simulation tools to analyse designs early in the design process with a virtual prototype, engineers can significantly reduce production lead times and avoid costly re-engineering processes. 
This webinar will discuss how to prepare for successfully set up and interpreting Acoustic simulations using ANSYS.
