Structured Meshing for Multi Element Airfoil

janetj · December 2020

Hello,

I am trying to create a structured mesh for a multi element airfoil on ansys meshing. Despite trying for several split patterns on spaceclaim, I am still unable to generate a structured mesh on the entire c-grid domain. Some splits are structured while some remain un-structured. Could anyone help me how I can obtain structured mesh on this C-grid for multi element airfoil?

Where are you meshing? Are you using Ansys Meshing?

Getting hex mesh in this geometry would require good amount of effort.

You can use prism + tri mesh. You would see lot of posts on forum about this. Also you can see some videos on youtube.

Hello Keyur,

Thank you so much for your response. Yes, I am using Ansys FLUENT for the meshing. And you are right, yes. I have spent nearly 15 hours on this to obtain Hexa mesh/mapped mesh and couldn't get it fully. Yesterday I was able to get some breakthrough by applying new splits as shown below. In the following pic you can notice that I am able to get Hexa on all the faces except for this little one circled red. I spent another 3 hours fixing this tiny face to get hexa but all attempts failed so far.

A close up is shown below. It is the pressure area of flap. beneath trailing edge. What would you suggest me do? And yes, I would confess that I am not really good with the meshing, although I am struggling well. When I apply for inflation, there is a cross mark on the Inflation despite mesh update. Please guide me in that area too if you could.
