The moving-mesh unstructured Finite Volume Method (FVM) provides a capability of tackling flow simulations where the domain shape changes during the simulation. In such cases, the computational mesh needs to adapt to the time-varying shape of the domain and preserve its validity and quality. In this paper, we present a vertex-based unstructured mesh motion solver with the polyhedral cell support which calculates the internal point motion based on the prescribed motion of the boundary.
