Causes for model crashes<br />
and how to avoid them<br />
• Computer hardware problems – hard to<br />
anticipate.<br />
• CFL errors – Using a very short Δt to guarantee<br />
that no violations will ever occur wastes<br />
computer time (that could be used for higher<br />
resol). But the Δt for an operational model<br />
should be somewhat smaller than for a<br />
research model.
