how to block a 120 degree part of a 2D vawt
 

Can anyone please help me on how to block a 120 degree part of a 2D vawt? I will be doing a thesis work on the performance of cambered airfoil but I am still on the stage of learning ICEM CFD to genereat my mesh.. Thanks :):):)

1. Create main block.
2. Associate edge and vertices.
3. Make four splits at leading edge, trailing edge, pressure side and suction. 4. Make O-grid around airfoil.
5. Set edge mesh parameters
6. Create UN-structured mesh.
7. Select solver and set boundary conditions
8. Output mesh.

thanks Far, but if you wont mind, i would like to request if you can make a step by step video tutorial on which edge and vertices should be associated to which curves and points. and the locations of the splits. Sorry but i am still lost with ICEM CFD. Thank you so much in advance.

Far, good day! I have successfully built my unstructured mesh for 1/3 portion of wind turbine.. My question now is how to make the whole three bladed rotor.. Do i have to copy rotate the geometry, blocks and mesh? or only the mesh?

I have tried copy-rotating the mesh but line elements would only appear for the original 1/3 part of my turbine. I am aware that i need to merge the nodes in order to generate the line elements for the whole rotor, but i think i am doing it wrong. I want to ask which nodes do i have to select to merge? thanks Far for your constant help..

Hi Michael!
Have you found the solution how to copy and rotating properly the mesh from the 1/3 part? I don't know it neither and it would be a great help if you could tell me, and I really appreciate it.
Thanks in advance!
