How to control the Inlet block mesh in turbogrid
 
Hi everyone,

There is a long inlet domain in my turbomachiery created with Bladegen. As I kown, Turbogrid just mesh single blade passage of a turbomachinery.Then in the Turbogrid , the long inlet domain takes on a triangle shape because the hub curve superposes with the rotation axis in the inlet domain. My problem is that the long triangle inlet domain always has bad meshes such as zero minmum angle near the hub curve, 180 degree maximum angle near the hub curve and large volume ratio.

Had anyone entercoutered such mesh problem? If the long inlet domain cann't be shorten, how to control the mesh.

Any idea of you will be appreciated.

Thanks in advanced!
