Hi,

 

I'm new to radioss. I'm carrying out roll over analysis on box as shown in attached image. i've assigned initial velocity along axis and got the box rotating, the problem i'm facing here is the box is being thrown upward and its not falling on the base.do i need to assign gravity? if so how?

for the same i tried giving initial velocity to the platform holding the box, the analysis showed platform pushing the box upward same as in first case. how to achieve a tilting scenario in this case?

    Hello Guru,

     

    If you are just tilting the plot form and expecting the box to roll over, then the initial velocity should not be on the box. It should be only on the plotform and you have to define gravity to box.  Defining gravity is simple procedure, you can refer the video link below for the same.
