Hi,

 

I have requested the acceleration vs time curve from Hypergraph (please see the attachment).Y axis shows me with a legend name of 'node data', does it mean the figures on the y axis depict magnitude of acceleration? If it is, does the unit in 'mm/ms2'? (the unit system I used for input are: kg, mm, ms, GPa, kN)

    Hi Thomas,

     

    yes it is mm/ms/ms.

    So the factor for acceleration of gravity (g) is 9.81e-3 (9.81e-3 mm/ms/ms = 1 g)

     

    Regards,

    Mario

     

    PS1: we are using t, mm, s, n, MPa ... factor is 9810 (9810 mm/s/s = 1 g)

     

    PS2: it looks, that you have to increase the number of points....
