Floating Objects with Initial Velocity & Connected Floating Objects

kevinxmu

Can DualSPHysics support defining floating objections with initial velocity? I need this to calculate some water entry issues. When i define the initial velocity, i encountered below error message:

"Combining floating and moving objects is not allowed, yet..."

Further more, in my project, there are multiple floating objections that are connected each other with mooring lines? Can i also model this in DualSPHysics?

Yes, you are able to specify an initial velocity to a floating object.



You should do it as such and not as moving + floating object.

For your question regarding mooring lines, it should be possible in DualSPHysics, refer to this pdf.

But I have never seen this in an official version of DualSPHysics, maybe the mooring line code has not been released yet. @Alex can correct me if I am wrong.

Kind regards

@Asalih3d Many thanks for the kind advice! I saw in the future version 4.4, there is some feature mentioned to be "Coupling with MoorDyn Library", is this maybe the mooring part?

@Alex Do we have any plan yet when the version 4.4 is expected to be released?

Probably, you can read more about the library / method it self here.
