Need an urgent help in Modal Analysis
I am doing an modal analysis of audio system attached to an Instrumental panel in a car using ANSYS 13 version software. I have used SHELL281 element for meshing and Black Lanczos method to extract the modes. This shell element has six degrees of freedom. I Have extracted 12 modes but the first six frequencies I am getting zero value. I am not able to interpret the results. request anyone to guide .
