Gas separator blocking
 
2 Attachment(s)
Dear all,
I need to do the blocking for such a gas separator:
Attachment 19569
Blocking in y-direction seems to be pretty straight forward. But how would you do the blocking of in- / and outlet pipes? I am not sure how to connect standard pipe blocking with the actual separator blocks... :confused:
I am happy about any ideas...

agdb file doesn't have any geometry. Can you upload .tin file instead of agdb!!!

Ok, I allways use the "workbench import" and import the geometry from the agdb file.
Anyway, here it is!

For the sake of an easy blocking , can't you simplifly the parts i highlighted in red

I already put round plates at top and bottom. I don't see any problem at these locations. What do you mean?

if you have too many elements in the up for example, they will be squeezed giving you then a bad quality. you have to add some quarter grid there. like in the picture below

Simplifying the geometry will not require you adding grid

Hi again,

What do you think of this?
1st step -> large ogrid along the y-direction
Attachment 19629
2nd step -> cut edges of long block above and below the inlet
Attachment 19630
3rd step -> create ogrid at inlet pipe. The orange line / arrows show the way of the ogrid.

perfect ;):cool:

No way, are you kidding?
So there is no way I can keep the o-grid of the inlet "inside", right? I have to let it leave on the backside in the same plane? I would prefer to have edges more or less parallel to the flow...

what you did is good
