Parameter control are used to adjust grid quality in temperature analogy method.Movement of boundary is considered as temperature boundary condition.Energy equation or heat conduction equation is solved to get temperature distribution.In temperature analogy method,node's temperature is regarded as node's movement.By using different thermal conductivity and source term,different temperature distributions/node's movements are obtained to meet requirements.It shows that the method solves effectively dynamic grid puzzle in fluid-solid coupling.

A mixed unstructured mesh generation method is proposed for complicated computational domains.Delaunay triangulation is applied based on initial meshes generated by frontal approach.It indicates that the mixed method shows good geometrical features and high efficiency.Characteristic based split scheme is applied to flows around a square cylinder in a channel with unstructured meshes generated by mixed method.
