I'm interested in the simulation for heat and mass transfer and expect the case, windshieldCondensation, to be applied to various fields.
For the case, /tutorials/heatTransfer/chtMultiRegionFoam/windshieldCondensation,
in the process to 60 sec, I consider that vapor in 'cabin' will condense on 'windshield_to_cabin'.
But the heat flux on 'windshield_to_cabin' dose not equal to that of 'exterior' even if this solver deals with unsteady state process.
I want you to explain this result.

Only two modifications done in the tutorial:
1) in the constant/thermophysicalProperties file, comment the C7H16 in the liquid subdictionary, and add C in solid:
```
liquids

}

}
solids
{
C
{
defaultCoeffs no;
// if defaultCoeffs no properties should be :

This is my 1st report and hope you guys help me out. I report this issue as I found nothing really related to this issue nor anyone could answer me in CFD online!!
I use interFOAM solver and using capillary-rise tutorial.
My problem is related to 2D usage of the capillary tube with an "empty" boundary condition. (I use g = 0m/s2).
I deal with micro-channels. So, I am usually dealing with length scales of 1e-6m and below.
As I understand from "empty" b.c. "nothing (no computation)" is being done along the empty dimension. What happens along other 2 axis is projected along the 3rd dimension.
As you see in the attached word doc, I performed several test cases over different length scales of the capillary tube and I see a severely diffused interface when I change my 3rd dimension. {Or to be more specific when the cross sectional area of the capillary tube is below 2e-10 m2}. Being an empty b.c., I would not expect this behavior and would expect a sharp interface for any value used in the 3rd dimension. Is there a limit based on length scales (or cross-sectional area of capillary) to which we can use interFoam? Important to mention that I tried even with a very small time step as well with no improvement of behavior. Also checked the case with a compression factor of 4 and grid refinement. Still the problem exists.
Really interested to know why this behavior is seen. As an example also attached a test case where the interface is getting diffused.
