This study numerically investigated an adaptive mesh refinement method based on experimental measurement. The difference of experimental and numerical results was propagated by an adjoint model of the radial basis function-based reduced-order model (RBF-ROM), which was derived from snapshots of a preceding numerical simulation. The incompressible Navier-Stokes equations were solved on the framework of the building cube method (BCM) for generating the snapshots and the mesh refinement was realized by utilizing the data structure of the BCM, i.e., a BCM mesh was refined by dividing cubes. The error of the numerical simulation was evaluated by two CFD runs with different mesh resolutions and the region of mesh refinement was defined by the inner product of the error and the measurement sensitivity obtained from the adjoint model of the RBF-ROM. By considering the measurement sensitivity, the difference of meshes after refinement appeared near the object, i.e., the region of mesh refinement was focused on the wake where the pseudo measurement was carried out.
