Overall Velocity of a Deformable Object

Overall Velocity of a Deformable Object

Overall Velocity of a Deformable Object

(OP)
Hello Everyone;

Could someone help me on plotting the overall post-impact velocity of a DEFORMABLE BODY. I have not any problem with the problem itself. But having trouble with the plotting of overall velocity of the body.

Note: I have tried plotting node based velocity but it gives me no idea how the big picture is seen.

Thanks in advance

RE: Overall Velocity of a Deformable Object

There is no output dedicated for that. The velocity is a nodal variable, so it is available per node.

You could request the mass and the kinetic energy for the part as history output and use that.
Or you can create a reference node inside your part and connect is with some spring to some nodes. Then you can evaluate the velocity of that node to get something like an average velocity.

Dear Mustaine
Thank you for the feedback. I will try your suggestion as soon as possible.
At the time being, I have found a solution for this problem. I took a slice of nodes perpendicular to impact direction and plotted their nodal velocity history then averaged them. It seems reasonable at this stage...
