How can I ensure ode45 does not take large time steps and ignore high frequency components in the forcing function?

I am working on the response of vibrational energy harvesters to a very abrupt forcing function with many high-frequency components. As you can see the peaks in the attached signal are very...

Why is the displacement response(see attached) of a composite cantilever beam obtained using Ansys APDL unsymmetrical about resonance?

I am simulating a cantilever beam on which a uniform pressure acts. I conduct a harmonic analysis such that the forcing frequency varies. The beam tip displacement is measured using ANSYS and...

What is the meaning of the error(There are elements with negative electric charge ...) in APDL (Harmonic response of a Piezoelectric unimorph) ?

I built a APDL model for the Harmonicanalysis of a Piezoelectric unimorph. The model is a unimorph with the steel substrate meshed using Solid187 and the piezo layer meshed by Solid227. The...

In ANSYS Multiphysics, how I remove nodes that are a part of two coupled sets?

Details: - I have built a model in ANSYS Multiphysics that represents a bimorph - A substrate with two piezoelectric patches on both ends. The piezoelectric patches are modelled using SOLID227...

Why do natural frequencies for a bimorph derived from "Modal" and "Harmonic" in ANSYS Mechanical do not match ?

I modelled a bimorph in ANSYS Mechanical(2015). It is a simple cantiliver structure. When I use Modal, the natural frequency of the first mode matches well with the theoretical value(188 Hz)....
