Hello everyone,
I am doing modal analysis for cantilever plate (attached file), I need to extract eigen vectors (mode shape vector of each mode) or modal matrix (matrix that hold all mode shape vectors).
I tried to extract mass and stiffness matrices and then solve an eigen problem using MATLAB but unfortunately the values of eigen values (natural frequencies ) are not matching with those obtained from ANSYS modal analysis
So, is there any way or APDL code that can be used to do this task directly ?
