Hi everyone!
I tried to do a linear static analysis and I found out that the stresses on CROD elements didn't change varying Beam section Areas or Young modulus E, and I don't know why.
Attached the hyperview output image.
Please help meee!

This could be a modeling issue (massless mechanism) due to the connection of CROD and SOLID elements. CROD has axial and torsional stiffness, and solid has only 3 translational stiffness. As a workaround, create a layer of shell elements on top of the solids, so the nodes connecting to CROD have rotational stiffness.
