no geometry in cfx mesh

mehrdadeng · June 15, 2009, 15:01

i have a important problem!!!!

i modeled cloud point to solid geometry.geometry is consist of assembly of blade and housing. And geometry is piecemeal

I imported assembly geometry to design modeler (attached fig).and enclosured blade. enclosure box is housing. I want to transfer model from design modeler to CFX mesh.after a long time meshing tab is empty(attached figure) and there is no geometry in meshing tab.

How can solve this problem???

Hi,

For blade modelling you need to model the surfaces accurately. How can the surfaces be accurate if you are just using a cloud of points approach?

maximum tolerance between my model and real model is 0.039[mm].my project isnt an industrial work.it is a student project.in that case 0.039 tolerance is not important.
can u help me please???

Hi,

It is impossible to debug this type of problem on the forum. You will just have to try some alternate approaches until something works.

thanks dear

hi dear
each other of blade and housing entered to meshing tab separatelly.
but assembly of them that have been enclosured dont enter to meshing tab.
