You could say it's revealing something about the physics used as input to the simulation.

my eyebrow raises from this with all of these cosmological simulations.

Just cosmological simulations?

What about FEM and CFD? Climate models? Economics?

To be honest, I don't even know what FEM and CFD are, and I'm not familiar with economic models. As for climate models, I raise both eye brows those

FEM: Finite element method

CFD: Computation fluid dynamics

Both common in industrial design for simulating the performance of a part-to-be.

Is your skepticism directed at all climate models or just the cutting-edge planet-scale politicized ones? I find our weekly forecasts quite useful, for example.

Weather models are definitely eyebrow raising. On days where there 0% chances of rain as the forecast, I receive .25". On days where it is >80% chance of rain, 0.0" of rain falls. Then there are days where it tells me with the accuracy of minutes of when the rain will start/stop. When their accurate, it's amazing. When they're not, it's very frustrating.
