3D simulation of bubble boiling in paraview
Hello everyone,
I am new in this forum and field too so i am just still learning. I am trying to simulate nucleate boiling in 3D with VOF and also I am at my initial stage. Initially I wanted to create just a semi-spherical bubble at the bottom plane of a cube.
The problem is the bubble does not show when I try to visualize it in paraview. I tried reducing the opacity. But nothing showed up.
Any help would be appreciated.
Here is my blockMesh file:
Code:
convertToMeters 1;
vertices
(
(0 0 0)
(0.031 0 0)
(0.031 0.031 0)
(0 0.031 0)
(0 0 0.031)
(0.031 0 0.031)
(0.031 0.031 0.031)
(0 0.031 0.031)
);
blocks
(
hex (0 1 2 3 4 5 6 7) (10 10 10) simpleGrading (1 1 1)
);
edges
(
);
boundary
(
bottom
{
type wall;
faces
(
(1 5 4 0)
);
}
outlet
{
type patch;
faces
(
(3 7 6 2)
);
}
walls
{
type wall;
faces
(
(0 4 7 3)
(2 6 5 1)
);
}
);
mergePatchPairs
(
);
and here is my toposetDict:
Code:
actions
(
{
name c0;
type cellSet;
action new;
source sphereToCell;
sourceInfo
{
centre (0.0155 0.0155 0);
radius 0.001;
}
}
{
name c0;
type cellSet;
action delete;
source boxToCell;
sourceInfo
{
box (0.0145 0.0145 -0.001) (0.0165 0.0165 0);
}
}
);
Also here is the setFieldDict file:
Code:
defaultFieldValues
(
volScalarFieldValue alpha1 1
volScalarFieldValue T 559.95
volVectorFieldValue U (0 0 0)
);
regions
(
boxToCell
{
box (0 0.026 0) (0.031 0.031 .031);
fieldValues
(
volScalarFieldValue alpha1 0
volScalarFieldValue T 559.95
volVectorFieldValue U (0 0 0)
);
}
cellToCell
{
set c0;
fieldValues
(
volScalarFieldValue alpha1 0
volScalarFieldValue T 559.95
volVectorFieldValue U (0 0 0)
);
}
);
The simulation ran properly but I really do not know where the bubble has gone when I visualize this in paraview |
