mid surface extraction              

 

providing mesh parameters

providing quality parameters 

mesh generation

 

improved mesh

BODY OF THE CONTENT

                                    To extract the mid surface for continuous varying thickness use middle-multi option from faces tab

                                 To assign the thickness to extracted mid surface on continuous varying thickness surface, take average value from the area and assign the value of average to that surface

To proper mesh flow                               

                                    Splitting the surf by cut option to max possible tiny macros so that it leads to get good mesh flow throughout the model and it reduces trias concentration

                                    Split, swap, join these three option helps to control the trias concentration

                                   Paste option helps to reduce trias on the surface

                                    Num (+\-) helps to maintain equal num of nodes at circle areas and edges

Conclusion

                                    Firstly, we should have done the all steps such as topology clean up, mesh parameters, quality criteria before going to mesh on the extracted mid surface after that cleaning the failure elements and smooth the mesh with appropriate tools such as smooth, cut, regenerate, split, swap, join and so on
