Hi everyone,
I'm going to simulate a floating object. A 2-d forced roll motion of rectengular structure. In two phase(air,water). Rectengular structure is floating but it is fixed in the center. It can just rollling. Which solver should i use? I looked the forum,then i find some solvers like interFoam and interDymFoam. Someone said "if your floating object is moving in the water due to wave forces" for interDymFoam. My structure is moving but just rolling. Should i use interDymFoam or interFoam. I'm confused. Thanks in advance, Kağan |

from the rather short description of your problem it is difficult to judge what you want to simulate and hence it is difficult to advice you which solver to use.
In general if the deformation of the body is small you should use interDyMfoam but if the deformation is large you may use overInterDyMfoam. But there are a few tutorials where cases with floating bodies are simulated. You my look there if you find one similar to your problem. Best Michael |

Hi Michael, Thank you for your interest. I found a tutorial like that. But I don't know that how can i make a forced roll. I couldn't find a forced roll between the tutorials which I search. Thank you in advance, Kağan |

Study mesh motion solvers of OpenFOAM before jumping into the unknown, IMHO.

you can find all available motion functions hear: https://www.openfoam.com/documentati...nFunction.html
a bit more detailed (maybe also not so resent) description of available motion functions is found here: https://openfoamwiki.net/index.php/P...dyMotionFvMesh |
