Hi all I am doing Flutter analysis of compressor blade, I am using ANSYS workbench for this.
Here i am giving the steps carried out for this analysis. 1. Modal analysis for 35350 rpm speed 1. Steady state analysis using CFX. 2. Unsteady case for flutter analysis by importing the mode shapes from modal analysis these are the major 3 steps followed, for flutter analysis we are going for Transient blade row method - Fourier transformations. I am getting negative volume error, even though mesh is fine, and time steps also large, please give some suggestions to overcome this |
