So true, so true   I can always tell who is a new user of simulation
software, they expect to get 9 (ppb, parts per billion) or 12 (ppt, parts per trillion) digits of precision out of our software.  I will go through my explanation of how simulation software is based on experimental data of 2 or 3 digits of precision and watch their faces change when they start to understand.

 You get them to understand?
 Could you try with policy makers?
 Yes, yes, I know you're going to laugh again.  This time with ample justification!

The worst thing is getting the young inexperienced engineers to understand that even though we are first principles simulation software, they think that any simulation is good for making billion dollar decisions on.  They need to validate that simulation with a pilot plant and extreme laboratory data first.  Few do nowadays.
