Problem with createBaffles - want to make master and slave internal patches

artymk4 · April 25, 2019, 04:04

I'm using foam-extend-4.0 so createBaffles utility needs to be run without createBafflesDict file the way it was done in OF2.1: https://openfoamwiki.net/index.php/CreateBaffles

I have faceZone which I want to convert to internal patch which will not impact flow. So I need to make two patches of type cyclic (master and slave).
When I run

Code:

createBaffles CK "(CK1 CK2)"

I get this:

Code:

Create time

Create mesh for time = 0

--> FOAM Warning : 
    From function polyMesh(const IOobject&)
    in file meshes/polyMesh/polyMesh.C at line 348
    no points in mesh
Converting faces on zone CK into baffles.

Found 896 faces on zone CK



--> FOAM FATAL ERROR: 
Cannot find patch (CK1 CK2)
Valid patches are 
17
(
inlet
outlet
casing_shroud-fluid_outlet
casing_shroud-fluid_inlet
casing_hub-fluid_outlet
casing_hub-fluid_inlet
ck_shroud
ck_hub
ck_blade_le
ck_blade_ps
ck_blade_ss
ck_blade_te
cyclic1
cyclic2
cyclic3
CK1
CK2
)


    From function findPatchID(const polyMesh&, const word&)
    in file createBaffles.C at line 113.

FOAM exiting

As you can see, I did create two new patches CK1 and CK2 in 'boundary' file. However it seems like createBaffles is expecting only one patch and I can't make it accept two.
I also tried to use -additionalPatches option, but no luck.
createBaffles works this way: createBaffles CK CK1, but then I am missing CK2 and I cannot set type cyclic to patch CK1.
Please help.
