[ICEM] No "apply" button" on Trying to rotate a block

Hazem24 · March 21, 2020, 21:44

Dear members,
I know this may sound simple but I've been stuck here..

I'm trying to create a hex mesh for a 3 blade wind turbine.
Using slicing I made a block surrounding one blade (since the blade is horizontal) and saved it as a part in the tree "BLADE_1"
Now I need the two other blades to have the same block, I'm trying to use rotate block, I selected the block and entered all the options and can't find the apply button and the middle click doesn't do it also. A
Any help

Regards,
Hazem

Would it not be easier to mesh only 1/3 of the geometry and make rotational copies of the mesh instead of the blocking? I have not done your approach yet but I guess you have to re-assign all edge associations even if you get the block pattern done?

Dear sir,

Your reply is appreciated!
Your suggestion sounds easier, but are you aware that 1/3 of the mesh would mean 1 blade plus 1/3 of the inner domain's and the outer domain's volumes?

If yes, then could you explain how I can do that?

You would cut your geometry in the CAD tool you use (DesignModeler, SpaceClaim or similar) so you only have 1/3 of it. Then just do the blocking how you did already. Create a mesh from it -> now you have 1/3 of it.
Then in the mesh tools there are options to make rotational or translational copies of the part. Make sure to merge coincident elements when doing this.

This is a good idea thank you for it!
But can I also make the cutting inside the ICEM?
Because I imported only the turbine rotor from design modular and there was a problem in importing the domain cylinders which I drew on ICEM
If not possible to slice on ICEM, could I import one blade and draw 1/3 of a cylinder in ICEM?
