What unit is the accn.?

Hello, 

Pl find attached image of the acceleration output wrt frequency.

My model is in 'mm' units and the material properties are all specified in in N, mm (except for the density, which is specified in tonne/cu.mm)

 

So, in the attached image file, the magnitude of max. acceleration that I obtained is 5400 along Y axis.

This should be 5400 mm/sq.s. So, 5400/9810 = 0.5 g is the magnitude. 

Am I right?

Pls share your views.

    Hi Karth,

     

    The solver is unit neutral so it is up to designer or user to maintain unit consistency.

    ok. Just for confirmation, in the above example, mm/sq.s is it right ?
