Hi,

I was trying to run some simulations using the Hyperelastic material model that have been introduced in SimScale recently. I am trying to run these for the SimScale blog article.

The interface allows for input of D1 parameter and allows this for any poisson ratio. However, if the poisson ratio is >0.4, the normal elements should demonstrate locking effects. This should be especially pronounced as it reaches 0.49 or 0.49999 etc. This would require mixed or enhanced formulation or reduced-integration elements to prevent locking.

Does SimScale automatically detect such a high poisson ratio & use a mixed or enhanced formulations? Because it did not show any such options for selection. In Abaqus, it allows one to choose these elements. So I was wondering, if SimScale is doing this automatically?

Thanks
