Hi fredo490
I want to run a 2-D moving mesh case with the top and bottom walls moving inside while the left and right walls moving outside. Unfortunately, the mesh node motion is not correct,and the mesh can only move in one direction.The key options are list below:
/////dynamicMeshDict
dynamicFvMesh dynamicMotionSolverFvMesh;
motionSolverLibs ("libfvMotionSolvers.so");
solver velocityComponentLaplacian;
velocityComponentLaplacianCoeffs
{
component x;
diffusivity directional (1 200 0);
component y;
diffusivity directional (1 200 0);
}
//////dynamicMeshDict

/////pointMotionUx

boundaryField
{
leftWall
{
type uniformFixedValue;
uniformValue constant 50;
}
rightWall
{
type uniformFixedValue;
uniformValue constant -50;
}
upwall
{
type slip;
}
downwall
{
type slip;
}
frontAndBack
{
type empty;
}

}
/////pointMotionUx


/////pointMotionUy
boundaryField
{
leftWall
{
type slip;
}
rightWall
{
type slip;
}

upwall
{
type uniformFixedValue;
uniformValue constant 50;
}
downwall
{
type uniformFixedValue;
uniformValue constant -50;
}
frontAndBack
{
type empty;
}

}
/////pointMotionUy


can you help me with this?
