    Mass 21 element and mass distribution in ANSYS apdl

    Hi, I have modeled 3D airfoil in Ansys apdl. there are 8 airfoil sections for which I have defined shell element, some thickness and all material properties including density. Now for modal analysis I need to modify mass distribution in each section such that mass moment of inertia of each...
