Dear All,

Some good news: I have just checked in a 6-DOF (6 degrees of freedom) solver in OpenFOAM. The code has been implemented by D. Matijasevic at University of Zagreb, Croatia and solves the translational and rotational motion of a body with springs and dampers. The code comes in several pieces:

- sixDOFODE ordinary differential equations class
- sixDOFbodies = multiple 6-DOF bodies
- top-level solver sixDOFSolver
- 2 tutorial cases: 1-D spring/damper motion and 3-D translation-rotation along the same lines.

Enjoy,

Hrv

Dear Prof. Jasak

Great !!

You never stop surprising us. That addition is going to help so many newcomers who struggle to put up together something that complex.

Thank A Lot

With Best Regards

Dear Hrvoje

this is indeed a very useful extension. I gather from some newer posts I read, that there are some people very interested in the 6-DOF capability. Are there any people in your Dept., in Zagreb doing research in marine CFD / hydrodynamics using OpenFOAM?


Warmest Regards
GK

Hello,

Actually, there is a number of clients I support with hydrodynamic interest. There is also a strong marine engineering department at the University, but I'm still working on "converting them"

Do you have something special in mind?

Hi

I assumed that they would - already - be faithful disciples of the project ;-). But - anyway, I know it is fairly difficult to switch experienced(*) users from one set of tools to another.
I'm trying to fast-pace myself to make up for some lost time. I wonder if it would be possible to gather some related material & examples from hydro/free-surface problems in the Wiki (if available)...(?)

Best Regards
GK

(*)I was witness in Split '00-'02 (on behalf of owners), when advice was sought to fine-tune some details in the form of the hull, but don't know the code(s) they used...in-house or other?

Dear Hrvoje,

could you shortly indicate how to get access
to the files that contain the 6-DOF solver and
the tutorials?

Thanks in advance,
Tim

Hi Tim

try this link

http://openfoam-extend.svn.sourcefor...enfoam-extend/

From there onwards please browse down to the stuff u need.

Hope that is the information you were looking for.

Regards
Jaswi

All in the public SVN repository:

The individual bits are:

http://openfoam-extend.svn.sourceforge.net/viewvc/openfoam-extend/trunk/Core/Ope nFOAM-1.4.1-dev/src/ODE/sixDOF/

http://openfoam-extend.svn.sourceforge.net/viewvc/openfoam-extend/trunk/Core/Ope nFOAM-1.4.1-dev/applications/solvers/basic/sixDOFSolver/

http://openfoam-extend.svn.sourceforge.net/viewvc/openfoam-extend/trunk/Core/Ope nFOAM-1.4.1-dev/tutorials/sixDOFSolver/

although I would recommend working with the complete SVN check-out.

Enjoy,

Hello!
I've downloaded all files and placed them into the corresponding directories, then I've tried to compile the sixDOF-solver, but without success:

What I was doing wrong?
