Implausible deformation in example

[Extraweich]

Hi there,

I hope this still reaches you. First of all, thank you for the nice tool. I tried the given example and just increased the pressure to see better what is going in the deformation.

You can see that the deformed state is rotated from the reference configuration, which seems implausible to me. I would expect an elongation in the x-direction and a contraction in the other two directions.
