Changing units in AVL Fire
 
Hi,


I have a problem with AVL Fire. I donít know how can I change units in this software.
I have made a part in GAMBIT and then meshed it. When I import it into AVL Fire, its dimensions are in m.
I want to change the dimensions to mm, but I don't know how?



Thank you,
Som

Changing units
 
Hi,

in FIRE all units are SI Standard units. If you import a grid (or other data) the SW assumes that SI Units have been applied when writing the data.

2 options:
a) you write out the Gambit grid again using [m] instead of [mm]
b) use MESH TOOLS > MODIFY > BLOW (0.001) to scale the grid from [m] to [mm]
