create two faceZones with single STL file - is it possible?
Hello all,
I am meshing an automotive radiator duct. Currently, I create a porous media cellZone with a single faceZone in snappyHexMesh, and then I use topoSet to split that faceZone into two faceZones: an inlet and outlet.
The geometry for the faceZones must be in one STL file, so that the volume for the cellZone is properly closed.
However, I would like to generate the inlet/outlet faceZones directly from the beginning, instead of running topoSet as an additional step. Does anyone know if this is possible? So far, all I can do is generate patches, which while convertible to a faceZone, do not allow the prism layers to travel through (something we need.)
My attempt:
Code:
geometry
{
A_testcar_5050.stl
{
type distributedTriSurfaceMesh;
distributionType independent;
name A_testcar_5050;
regions
{
WALL_L_POROUS_Radiator_8_8 { name wall_l_porous_radiator; }
WALL_L_body_8_8 { name wall_l_body; }
WALL_L_body_small_2_2 { name wall_l_body_small; }
}
}
internal_fluid_l_porous_radiator.stl
{
type triSurfaceMesh;
name internal_fluid_l_porous_radiator;
regions
{
INTERFACE_L_POROUS_radiator_inlet { name internal_l_porous_radiator_inlet; }
INTERFACE_L_POROUS_radiator_outlet { name internal_l_porous_radiator_outlet; }
}
}
};
// Castellated Mesh settings
castellatedMeshControls
{
......
refinementSurfaces
{
A_testcar_5050
{
level (8 8);
regions
{
WALL_L_POROUS_Radiator_8_8 { level (7 7); }
WALL_L_body_8_8 { level (7 7); }
WALL_L_body_small_2_2 { level (9 9); }
}
}
internal_fluid_l_porous_radiator
{
level (8 8);
cellZone fluid_l_porous_radiator;
cellZoneInside inside;
regions
{
INTERFACE_L_POROUS_radiator_inlet
{
type faceZone;
faceZone internal_l_porous_radiator_inlet;
faceType internal;
level (8 8);
}
INTERFACE_L_POROUS_radiator_outlet
{
type faceZone;
faceZone internal_l_porous_radiator_outlet;
faceType internal;
level (8 8);
}
}
}
}
