I tried loading a sketch and got an error that the Granite kernel could not launch 2D geometry and to try the Mechanica launch method. When I do this, it actually doesn't launch at all. Any ideas?
I agree here with Jon. Knowing some of the geometry you've dealt with in the past, you might be able to look at portions from a 2D axisymmetric aspect. However if you were going to run in 3D (quarter/half symmetry, or full model) I would also suggest refining the mesh in the cone as you can see that teh flow field is following the coarser elements and as you refine you'll start to see tht the results become more symmetric.
I would also encourage you to run ADV5 (in 2014/2013) or ADV2 (otherwise) as it will help with the results in applications like this.
In 2010 we only had ADV2, which would be a good start for this model. If you were to update to 2013+ you would have the option of ADV5 which is a newer/improved version of ADV2
