Dear OpenFoamers,

I have a similar question to the previous thread, it is about units. I would like to be in cm instead of m, therefore do I need to change the units from, for example, [0 1 0 0 0 0 0] to [0 .01 0 0 0 0 0] and [0 2 0 0 0 0 0] to [0 .0002 0 0 0 0 0]? or can I just leave the units as is and change the values that I have into cm?

Sincerely,

Benjamin

nope you can not
look at for dimension analysis at fluid mechanics book or look at here
those values just define in a equation whether those mathematical terms can be add or subtract from each other?
