Hello Guys!
I do need your help. For my project I need an similar case to the tutorial oscillatingInletACMI2D. The only difference is that instead of the solidBodyMotion Solver I need to use the dynamicMotionSolverFvMesh for my model. After changing all the stuff and defining the pointMotionUy File I do have problems with the Interface, because the mesh also changes on the right side (which it should NOT). The mesh then degerenates and the simulation diverges.
Have you guys had any similiar problems using ACMI together with the dynamicMotionSolverFvMesh?.

Here's my Code:

dynamicMEshDict:

dynamicFvMesh dynamicMotionSolverFvMesh;

motionSolverLibs ( "libfvMotionSolvers.so" );




solver velocityComponentLaplacian;



velocityComponentLaplacianCoeffs
{
cellZone inletChannel;
component y;
diffusivity directional (0 40 0);
}

pointMotionUy

dimensions [0 1 -1 0 0 0 0];

internalField uniform 0;

boundaryField

{
moving_top
{
type uniformFixedValue;
uniformValue constant 0.2;
}
inlet
{
type slip;
}


wall
{
type uniformFixedValue;
uniformValue constant 0;
}

fixed_bottom
{
type uniformFixedValue;
uniformValue constant 0;
}


outlet
{
type uniformFixedValue;
uniformValue constant 0;
}

defaultFaces
{
type empty;
}

ACMI1_blockage
{
type slip;
}

ACMI1_couple
{
type slip;
}

ACMI2_blockage
{
type uniformFixedValue;
uniformValue constant 0;
}

ACMI2_couple
{
type uniformFixedValue;
uniformValue constant 0;
}

}


THANKS A LOT!
