lsdyna post analysis

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....
