Detailed Description

Raised when the moment closure cannot serve this model: the linearization at the fixed point is not hyperbolic, or the drift has left the simplex.

A non-hyperbolic fixed point cannot be detected before the mean is solved, so fluid_minnormal_applicable cannot decline it in advance; the runner catches THIS exception, and only this one, to fall back to a first-order method when the moment closure was RESOLVED from default rather than asked for by name. Catching a plain NumericError there would also swallow a singular Jacobian or a failed integration, which are defects and not model properties.
