Hi, I want to create mesh around a blunt body as shown in image.

Sorry for not drawing straight lines in drawing.

How can i create such mesh?

Thanks for answer. How do I do meshing in wake region behind the truck. BTW Can you tell me name of tutorial as I don't find any similar tutorial, so that i can find from tut folder.

The 2D Car tutorial covers this as well as how to script the process.

As for wake refinement, there are several techniques. You could use hanging node refinement or you could insert an o grid into the trailing edge blocks to increase node counts without propagating all the way to the far field boundaries. Of course, many users just go with increasing the distribution in the area of interest and don't mind it propagating to the boundary.

Thanks psymn. I will try meshing with that model.
