Tensors are normalised when computing the eigenvalues. There was a mistake in the normalisation which can lead to severe numerical instabilities in some (rare) case.

When definining finite strain strategies in the
castem interface, a regression was introduced in version \(3.0.0\), if only one finite strain strategy is defined: in this specific case, one define two behaviours (in fact the second is barely an alias for the first one):
The regression was that the
ModellingHypotheses symbols was only defined for the second behaviour.
