Tank Sloshing Research

Hello all,

I am trying to replicate the following video : https://www.youtube.com/watch?v=c-piZAVm51c

I am very new to CFD and I was wondering if anyone can help me with a small problem. How can I make my mesh move back and forth?

Hi,

I am also new to OpenFOAM. Are you using openFoam 5? If so try the following instead of the existing one (SDA) on the 'dynamicMeshDict' file of sloshingTank3D in tutorials

dynamicFvMesh dynamicMotionSolverFvMesh;

motionSolver solidBody;

solidBodyMotionFunction oscillatingLinearMotion;
oscillatingLinearMotionCoeffs
{
amplitude (0.3 0 0);
omega 126;
}

This works for me. Change amplitude and omega as you need.
