[FLASH-USERS] Validation results

[Tomasz Plewa]

Hi Abdekhak -

I understand that by "resolving" you mean recovering analytically 
established relations for the instability. It will actually take a 
little bit more than that since to model validation actually requires 
knowledge of both observational and numerical errors. So when using 
FLASH, you want to put error bars on, for example, growth rate estimate. 
Then you will be in position to see whether  you numerical results along 
with their error bars match observations within the corresponding 
observational errors. A procedure of comparing those results inolves 
certain metric, and defining that metric is not always an easy task.

Good amount of information is given in a book by Oberkampf and Roy,

which I strongly recommend.

Hope this helps -

Tomek
