H-O-H-Mesh on T106A Turbine Blade
Hello all -
I have searched up and down this forum and online for a tutorial on how to create an H-O-H-grid for a turbomachinery problem. I have completed most of the tutorials on the portal (2D pipe, 3D pipe...), but none of them seem to cover my specific problem. I noticed people mentioning a stator tutorial, which could be useful, but I could not find it. I did find the .zip files of ICEM PowerPoint lectures somebody posted. They were somewhat useful, but still didn't answer my problem. I will be importing the mesh into CFX. Here is the geometry:
The first square inlet region is the first H-grid section. I then want an O-grid around the airfoils (the top section is the pressure surface, the bottom is the suction surface), followed by a transition to another H-grid in the rectangular outlet.
I blocked the domain like this:
With the associations shown:
The thought process here is that I want the first and last blocks to be simple, structured H-grids. The airfoil block has an O-grid split (the blue square). The diagonal block after the airfoils will be a transition region between the O- and H-grids. I'd like the O-grid to be orthogonal to the airfoil, and refined for proper boundary layer capturing.
I know how to make the entire domain unstructured prisms. I know how to create a fully structured H-mesh with specified nodes. I don't know how to implement both in the same simulation.
Any help would be much appreciated, whether it's simple advice, tutorials, or (bonus) instructions.
Any help? I will be taking ICEM workshops over the summer when we receive our new budget, but I have a conference before then and need to have this simple simulation to present.
Please don't think I'm being lazy. I've blown 6 work weeks on this already, but can't seem to get any help.
I have the same problem as yours.
I Think you can help me now. Do you have any idea how to create HOH grid?
can you just sketch and show how you want a H-O-H grid (free hand sketch). if possible can you upload the geometry, so that i can make you the required topology for you.
can you help me to have some general info and some pics of HOH grids.
I'm just beginner in HOH.
TNX a million
Hey guys -
Please read this thread: http://www.cfd-online.com/Forums/ans...-elements.html
It solved my problems.
