Transient structural using solid65 element
My goal is to simulate transient structural analysis for a simply supported beam. How to specify solid65 elements for the beam. Is it possible to model the beam without rebars? I need to obtain a crack pattern for the vibration load applied. I already modeled the beam in static structural and modal analysis, I tried to change the elements to Solid65 using APDL command snippets. But it is showing errors. How to solve this problem?

Element type 1 is not the same shape as SOLID65. Switching to a
different shape is not allowed while elements of type 1 exist.
