I want to know the basic difference between the structured and unstructured mesh

Hi Dears I am looking for easy codes of unstructured mesh generation . If you have C codes or Fortran Codes , please send it to me . Thanks

Dear Dipa,

a structured mesh looks most generally like a warped Cartesian coordinate system with each node of an element represented by an (x, y) coordinate. But curved rectangles come in to picture because of odd geometry shapes and this makes it difficult to resolve corners and sharp edges. Because of this reason that unstructured meshes came in to picture. unstructured grids can resolve corners and sharp edges much better than structured grids and hence used for complex geometries. For solving flow equations you need neighboring node information which you can easily get with structred grids than unstructured.

sir,

i am malathi.i just completed my M.Tech.I want to know the basic difference between structured mesh and unstructured mesh.please send me the information.

Thanking you sir

yours sicerely

Hi all

I am new to this blog and taking advantage of their knowledge. I have a question.

What is the best choice for modeling a wind turbine (helical Savonius) Phoenics or Star CCM +?

The simulation will have an inflow, outflow and a rotating geometry (wind tunnel).
