Refined version that includes wall layers. - this causes significant pressure spikes using the default AMI dynamicFvMesh dynamicMotionSolverFvMesh; - enabling topology change where a 1-to-1 connectivity is established across the AMI leads to a much smoother pressure trace. Ony change needed is to the motion solver: dynamicFvMesh dynamicMotionSolverFvMeshAMI;
