We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Benjamin,

I apologize for forgetting to send my files, I made a mistake.

I saw your answer on the forum and I have a question. Does your model account for the viscoelastic variation according to the snippet command? Also, could you verify if it doesn't show the following message in the solution information:

For material 2, the harmonic viscoelastic model requires two elastic constants. The shear modulus experimental data will be used with the real Poisson's ratio input via the MP or TB, ELAST command, and the imaginary part of Poisson's ratio will be set to zero.

When I run my model, it doesn't account for the snippet command, but it still runs. However, the results are incorrect, when comparing with the simulation without the viscoelastic material.
