Very low natural frequency obtained in natural frequency

Dear All,

I am running a simulation of a dragonfly wing. My analysis is natural frequency ( modal ) with nonlinear material. I am supposed to obtain at least 20-40 Hz but now my max Hz is only 0.08 Hz... Is there something that I should fill in my analysis parameters. Why is my natural frequency so low? I used plate/shell elements

My guess is that your results are wrong because your input is wrong. Most likely, the constraints or materia properties have a problem.
