Detailed Description

The reference's MException('LINE:FluidNonHyperbolic'), as a type.

IT HAS TO BE DISTINGUISHABLE FROM EVERY OTHER FAILURE. A non-hyperbolic fluid 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. What fluid_lyapunov reports about the fixed point it linearized at.
