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,

Have you completely defined the hyperelastic property? as shown in the engineering data field as per below?

Please ensure all the fields are filled out. If you did, then the error messege might be due to your parameters are inconsistent with monney rivlin(5 parameters) materials. This could be due to missing or incorrect material constants or parameters that are essential for the material model to function correctly. It is also important to ensure that the experimental data collected from tests, such as a uniaxial test on an elastomer sample, is correctly imported into the Engineering Data module.

A relevant discussion you can find in the below link about neo-Hookean material.

Hope this helps.

Thanks

Aurojyoti.
