Good morning,
I'm having problems in defining a fan boundary condition between two blocks. While, via GUI, the problem can easily be solved by clicking on the "select cononections" tab, I'm struggling to find a solution using Glyph.


I should create an automated mesh for an optimization loop, therefore I've got no other alternatives than scripting this out.


Any guess?

Right-click in message window and turn on journal messages.
Then you will see how GUI is doing it.

When applying a BC to a blk connection, you must specify which "side" of the domain. This is done with a 3-D {blk dom} register or a 2-D {dom con} register.

See Glyph Docs for pw::BoundaryCondition

get blk1 [pw::GridEntity getByName "blk-1"]
get blk2 [pw::GridEntity getByName "blk-2"]
get cnxnDom [pw::GridEntity getByName "dom-1"]

set bcIn [pw::BoundaryCondition getByName "in"]
set registerBlk1Cnxn[list $blk1 $cnxnDom Same]
$bcIn apply[list $registerBlk1Cnxn]

set bcOut [pw::BoundaryCondition getByName "out"]
set registerBlk2Cnxn[list $blk2 $cnxnDom Opposite]
$bcOut apply[list $registerBlk2Cnxn]

good luck

Thank you! I was not defining the sides. You saved me!

No Problem.

Also, to clarify. The third, Same/Opposite register value is only required IF you have a self-connected block (e.g. an O-topology block).

The yellow, wake domain in this video has the same block on both sides and would require Same/Opposite to properly define the register.

The Same/Opposite refers to the orientation of the domain (Edit, Orient...). Same == "Same side as the normal".

Updated example:

get blk1 [pw::GridEntity getByName "blk-1"]
get blk2 [pw::GridEntity getByName "blk-2"]
get cnxnDom [pw::GridEntity getByName "dom-1"]

set bcIn [pw::BoundaryCondition getByName "in"]
set registerBlk1Cnxn[list $blk1 $cnxnDom] ;# Same/Opposite optional
$bcIn apply[list $registerBlk1Cnxn]

set bcOut [pw::BoundaryCondition getByName "out"]
set registerBlk2Cnxn[list $blk2 $cnxnDom] ;# Same/Opposite optional
$bcOut apply[list $registerBlk2Cnxn]
