FEA Dynamic Analysis
FEA Dynamic Analysis
(OP)
Hi, I'm working on a project that entails calculating the frequency response on a steel structure made with 2D elements.
Does anybody knows a rule of thumb to define the minimum size of elements in order to be able to obtain reasonable results for a certain frequency?
Say for example that I would like to calculate the frequency response on a 10 mm thick plate at 300 Hz.
Thank you!

h_max = λ/6 = c/6f
But I haven’t heard about such requirement/recommendation for structural dynamics.
