Hello FOAMers,
i noticed the solidBodyMotionFvMesh feature in the dynamicMeshDict, where to specify coefficients for SDA (ship design analysis) or SKA (sea-keeping analysis) in the sloshing tank tutorials. I want to adapt this capability for cases with moving meshes via ggi, e.g. harmonic oscillations of rotating mesh parts. Does someone already work on this issue? I didn't find an appropriate hint within this forum. I have in mind to create something like a harmonicGgiFvMesh or something similar, but maybe there exist a quite smarter solution to force a ggi mesh motion with several parameters like the SDA/SDK coefficients? Thanks in advance /Stefan BTW: I use OpenFOAM-1.6-ext. |

Hello again,
Just a reply to myself... Following the link http://www.cfd-online.com/Forums/ope...1-ggi-bug.html you will get an idea how to do that. Another thing that come to my mind: How is it done, that GGI motion isn't enforced by such parameters rather than a solution of the ODE motion solver itself (e.g. decay of turning bodies due to viscosity)? Does anybody have a clue about that? Its obvious, that these things already challenged with 1.6-ext, as you can see in examples shown by WIKKI (i.e. drop of cylinder, capsizing box, etc)... Regards, /Stefan |
