VUInter seemingly cause elements at contact edge distortion.

Hi there, I am trying to use VUInter in Abaqus/Explicit 2D axisymmetric model, but always encounter error：“The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element.” After testing using a simple 2D axisymmetric simulation, which consists of: two blocks forming contact pair; a most simple VUInter describing contact stress sc=-k*g when g<0, and sc=0, otherwise. Strangely, even though the testing simulation didn't take any action and just let the system to relax (it

How can I do this? And what are the ways to do this? (Grit

How can I obtain the harmonic response results?

How can I obtain the harmonic response results? I have already completed the frequency step as a preceding stage, but when I run the harmonic response, no results appear.

How do I set up shape optimization to avoid this ugly mesh?

That is the setup: The optimization result is this Clearly creating an artificial stress concentration (singularity, really, due to the sharp corner). Cycle 5 actually produces a reasonable 15% reduction of max vm stress. Isn't there some control that would penalize the creation of the sharp corner? Any hints will be appreciated.

Interpretation of stress - discrete orientation scenario

Hello, I came across the following documentation mention - When a user-defined orientation is used in an element section definition, the stress, the strain, and the element section force components are output in the local system. By default, Abaqus/CAE displays element-based field output results in the coordinate systems defined during preprocessing and node-based field output results in the global coordinate system. So, basically if I have a local CSYS defined in the .inp file, my S11
