Help for Autoblade Fitting while export the geomturbo file

Chaoman · January 15, 2016, 07:22

Hi, everyone,

Now I am optimizing a centrifugal compressor with Design 3D. The periodicity of the blade in the target geomturbo file is 12. After I finished the fitting work, I export the paramitric geomtry and then check the periodicity in the geomturbo file. I found that the periodicity is default number 4. This troubles me while the following step of CFD-Screening. How can i get the correct periodicity of the blade while export the geomturbo file?

Who know the answer of this problem? Any help will be welcome.

hi . i want to optimize my centrifugal blade with design3d , but in screening part, i have an error that says autogrid can not do meshing and you have negatives volumes . seperately when i want to build mesh of my geometryi have no negative volumes in double precision but i have it in single precision . thanks

Dear Chaoman
Try a simple geomturbo file which is available among Numeca tutorial files and check if the same problem is seen there.
