I am constructing a code to solve the eigen problem of a solid structure,.
I use the step-36 as a sample, but I don't know how to write a new one for 3D
solid structure with tensil modulus E = 2.0e11, poisson ratio = 0.3 and
density = 7.85e3.
If you have any other samples or ideas, please help me.
Leonhard:
what have you tried already? Have you looked at the elasticity tutorial
programs and how they construct (i) finite element spaces and (ii) the
stiffness matrix? If you understand that, you will also understand how to
solve the eigenproblem.
