Hi Everyone,

It may be my ignorance but I could not understand the 6 dof forces data.

As an example when it is drawn "Fz" from the decay of sphere tutorial, the result is below:

Why is this single force component (Fz) has three phased look?

Regards,

Could you upload your setup for us to check?

My results from the "9_15 Heave Decay of Sphere" tutorial case as is.

Still not sure what you mean.

Let me try to explain but I am not sure I can.

When I draw the force z vs time got the plot at the link of the first post.

I expect a continuous (or near continuous) dots as represent a single curve, instead when these dots connected there is very large zig-zags on the force curve. Indeed these dots seems like three different curves with a phase difference in appearance, isn't' it?

Is this due the low resolution of the grid or is this the normal behavior?
