hi..
i am trying to change the solid element by the eqivalent shell element to reduce the computation time.
i got the modal analysis result within 10% for solid and shell element but % difference in the stiffness in x y and z direction is more than 20%.
i am using the solid 185 and the shell...
hi
i am working on the same problem. i do also have the same problem but i got the results for natural frequency of the shell model and solid model between 10%. that is fine enough and i am going to optimize the shell thickness to reduce the % error to get between 1-2 %.
i have one problem in...
