displacementMotionSolver on different mesh region
displacementMotionSolvers access points0 through
IOobject io
(
"points0",
instance,
mesh.meshDir(),
mesh
);
This should be
IOobject io
(
"points0",
instance,
polyMesh::meshSubDir,
mesh,
)
instead since the name of the mesh is already encoded in the mesh.name() and mesh.dbDir()
