OpenFOAM - Provision for allowing freedom for motion for the object under study

Provision for allowing freedom for motion for the object under study

My project for PG is on maneuverability of ship. I am using openfoam for simulation. My question which solver i should use and where in solver i should add the details of degree of freedom?

Thanks and regards

Dear Mohammed,

interFoam would be a good place to start as it has dynamicMesh capabilities as well as tutorial cases for your application. Please refer to the following tutorials for your reference (OpenFOAM V9):

$FOAM_TUTORIALS/multiphase/interFoam/laminar/sloshingTank2D3DoF
$FOAM_TUTORIALS/multiphase/interFoam/RAS/DTCHullMoving
Useful information on dynamicMeshing in OpenFOAM: Guerrero, Joel (2022): OpenFOAM advanced training. Moving meshes, rigid body motion, adaptive mesh refinement, and overset meshes. figshare. Presentation.

That is the reason focus on you must specific groundwork well before authoring. Will be possible to more desirable blog posts in this manner?

The position of a single railcar (engine) moving along a track has one degree of freedom because the distance along the track determines the car's position dinosaur game. A train of rigid cars connected by hinges to an engine still has only one degree of freedom because the shape of the track restricts the positions of the cars behind the engine.
