they aren't connected.
upload your dbs file

Regarding the colors they aren't connected, indeed. Should i connect them manually?

On what server can i upload the file? Or can i mail it to you? (the dbs file is 3Mb)

Ok I checked you model, and the volumes are connected, so it is ok from this side.
Now since you have meshed it, have you checked the max skew cells? (examine mesh icon and check how many cells exceed 0.9) There are sharp angles which makes failed some surface mesh.
Is the check-mesh in fluent ok?

Hi,

Thanks for doing this! Could you tell me how you did it, or send the file back?

I know the max skewness is to big in my mesh right now. Some off the cell exceed 0.95 (8 cells)
I'm trying to resolve this, but i think i will have to change (or smooth) the angle of the upperdeck.

The check mesh in fluents gives a to large skewness and aspect ratio. :o

ok what you can do:
for each sharp angle (like the picture):
*create a vertex at location on one of the edges which generates sharp angle
*do the same for the other edges
*split each surface (here 2) with the 2 vertex you created
*merge each surface containing sharp angle with the hull surface (not the other surface with sharp angle)
*the sharp angle should dissapear, and the problem will be on the short edges (split from vertex). But this issue can you solve by refining the mesh around the edges

Thanks to mAx this problem is solved! :)

There's a size function attached to the hull so the 'inner brick' can be meshed with Hex Core Native and the skew is limited to 0.92.

The outer brick is also meshed with Hex Core Native, so the total amount of cells is about 2 000 000.

I think almost everything is explained in the topic.
The major problems were:
Split the domain
Merge the surfaces of the hull
Try to limit the sharp angles by splitting the surfaces and merge the part with the sharp angle.
Use a SF to limit the skewness.

Thanks for al the help!

Read file with command "NBLOCK and EBLOCK"
 

Hi,

I´m working with ICEM CFD, I´m importing mesh to ANSYS about disc spine but It generated *.txt. This file have commands i.e. "CMBLOCK, EBLOCK, NBLOCK" My cuestion is , Can to read these commands in APDL MECHANICAL of ANSYS :confused:

How do I do this?
