How do i solve this problem about Modal Analysis of Cantilever Beam (Natural Frequencies, Mode Shapes) please HELP ME!!
One solid element through the thickness is not sufficient.
Add a Mesh Method of Sweep to the body. Select the top face as the source face. Set the number of elements for the sweep to 4. That will create 4 elements through the thickness. Then try to solve.
A better method is to go to Geometry and use a surface instead of a solid. The surface can be assigned the thickness. Then a single shell element will capture the stiffness properly.
