Traditional structured/unstructured mesh generation technique costs long computing time.Usually,for a two-dimensional simulation,it costs hours;for a three-dimensional one,it needs several weeks to generate a high quality mesh.Besides the time,these methods will modify the local design if the deformed meshes are generated.To reduce the generation time and keep high quality close to sharp corners,we introduce a new mesh generation method which is a cooperation on cut-cell and adaptive mesh refinement(AMR)techniques.Here,tc simplify the call of the method,we name it CAMR(cut-cell adaptive mesh refinement).CAMR belongs to field of the immersed boundary method,but it is more advanced.Because close to the boundary of a design,the quantity of the mesh refines to the highest level.The detail of the design is reserved everywhere with CAMR.
