[ICEM] using Multizone method

Daniel_Khazaei · July 17, 2016, 17:55

Hello friends

Is it possible to get a multizone mesh for this geometry?

I have tried to start from 2D surface blocking after building topology, all the surfaces are OK!

but when I try to create a 2D to 3D fill, I get a error:

1 unstructured part did not mesh (the block near the hull) or the Ogrid failed when selected!

mean while I have tried to learn Ansys Meshing but I have a weird problem!!!

Fluent reports different quality metrics in theses two situations:

1) export a .msh file from ansys meshing and read it to fluent separately!

min orth quality: 0.15
eq skew: 0.84
Maximum Aspect Ratio = 2.38035e+01

2) use workbench and fluent module step by step! (directly read from meshing step in the module)

min orth quality: 0.2
eq skew: 0.74
Maximum Aspect Ratio = 1.69214e+01

what is the problem?

Hi all,
I using multizone interactive with ICEM to mesh my geometry, and i try to load script file.
My meh failed, and this message appears to me
MultiZone could not generate a valid mesh.
why this happen , all i did change number of nodes?
any one can help.
