Hi everyone,

I tried to make a transient simulation of a piezoelectric sensor (pulse excitation + prestress). It converged but the voltage signal didn't fit with my measurement result. So I decided to add a plate to the model that should represent the emitter that excites the sensor. Unfortunately this version didn't converge anymore (see convergence plots).

Looking at the Newton-Raphson Residual Force plots i found out that mainly in the areas where the symmetry plan intersects with my nonlinear contacts (frictional, non-frictional) there are high residual force values. What's the reason for this and can I reduce this values with changes of my contact settings?

Best regards

This will need some discussions and look at the model, which can be confidential I suppose?
Can you please create a support request in the customer portal and I will help you?
Or are you an academic perhaps working with the company, and then have been suggested to use this forum for any technical support?

thank you

Erik

thanks a lot for the fast response. Well I'm a PhD student so somehow an academic but I haven't been suggested to especially use this forum.
I will create a support request and we can continue there.

Best regards

Yes please do that and in the SR please mention my name.

Thank you

Erik
