If you are interested, I wrote a small tutorial on how to add the parabolic velocity boundary condition from OpenFOAM-1.4.1-dev into the distribution by OpenCFD by using dlopen.

Here you have the temporary link (I plan to move it in the future). Tell me if you find it useful or not.

Håkan, Does the parabolic inlet B/C (explained nicely in the wiki) work for both 3D and 2D cases?

[inddzen]

Hi Håkan,

Thanks for the link, great stuff and well explained.

I did exactly as you wrote, and I made a simple test case on icoFoam which apparently worked, but I need to view the results to be sure

The problem is that I got this error while trying to run paraFOAM!

Any idea???

[msrinath80]

inddzen, I remember seeing a similar error in this forum. The simplest fix is to comment out the libs ("libmyBCs.so"); section in controlDict and then start paraFoam. This should let you visualize the velocity field without problems. The entry in controlDict is required only when running icoFoam.

[hani]

inddzen, paraFoam does not recognize your new boundary condition. I don't know how to do that at the moment. However, if you run your case until you write out a new time directory you can see that there is also a 'value' entry in the boundary condition. paraFoam will open the boundary condition as a default patch field and apply that value. There is however still a problem: you must make sure that there is a 'value' entry for the boundary condition also for the '0' directory. Add the following to your boundary condition:

value uniform (0 0 0);

Then of course the visualization of the boundary condition at time 0 will show no velocity at the inlet. Another way to do this is simply to remove the '0' directory when you have any new time directory. In any way, you should now be able to see the boundary condition in paraFoam for times > 0.

Srinath, This parabolic boundary condition should work also for 3D cases with 2D inlets, but the profile is still a 1D function in a cartesian coordinate system. Have a look at the source code.

Håkan.

Hi everybody!
Håkan, your tutorial is simply great and has proved very useful (not only for the parabolic profile, but especially for future personal BC implementation), so I wanted to thank you (and every people that provide useful modifications). Can you explain the syntax in the line libs("lib_name") ? OF searches directly in $FOAM_USER_LIBBIN? It would work equally well if the library were in another directory?
I apologize in advance if my question is obvious...
thank you again and bye,
Marzio

[hani]

Hi Marzio,

Yes, OF searches for the library in $FOAM_USER_LIBBIN. Without testing, I think that you should be able to locate your library anywhere as long as you add that path to your $LD_LIBRARY_PATH. Try it yourself.

Håkan.

[marziolettich]

Thanks Håkan! It may seems strange to those familiar with OF but these details are sometimes the part in which we newbies get stuck!
Now it's my turn to give a little contribution: the source file "parabolicVelocityFvPatchVectorField.C" (whose link is in your tutorial) contains a little error in the row in which the patch coordinate is computed. As it is, it gives a local coordinate that varies from -0.5 to +0.5 but we obviously need a -1 to +1 coordinate, so it is sufficient to multiply coord by two.
Well, now I get back to work (I have to make some little modification to obtain a parabolic profile only on a part of the patch, but it shouldn't be a difficult task!)
Thanks again for your answer and bye,
Marzio

[cpplabs]

Hi,
Is there a way to modify the boundary condition inside the application? For example, I have a function to calculate the velocity profile of non-Newtonian flow at the inlet, and need to set the values on the inlet patch. How to directly modify the values on a patch ?
Thanks!

[gschaider]

Hi J.T!

You might want to look for the dicussion on the timeVaryingMappedFixedValue-boundary condition. It might do what you want to do (but I havn't used it myself yet). In the worst case it might be a good starting point for your own developments

Hello,

I have a question about parabolicVelocityFvPatchVectorField and similar patch fields - they have one or two virtual functions:

virtual void updateCoeffs();
virtual void evaluate();

I observe, for field T updateCoeffs is called 3 times (I have only 2 relevant boundaries) before solving and evaluate after.

My question is: what and when do those function calls?

[leo]

Hello,

I've been reading this discussion board for some time and wish to sincerely thank all who contributed! Also great thanks to Hrv and others for this awesome open source CFD code.

I've implemented a variant of the parabolic velocity BC from Hrv and others. It works great for a simple cylindrical steady laminar flow problem using simplefoam.

My problem comes in when I try to implement it with an input with several blocks in it (10 to be exact). I get the following error message:


Starting time loop

Time = 1



--> FOAM FATAL ERROR :
gradientInternalCoeffs cannot be called for a defaultFvPatchField (actual type parabolicVelocity)
on patch inlet1 of field U in file "/home/leo/bif032208a/0/U"
You are probably trying to solve for a field with a default boundary condition.

From function defaultFvPatchField<type>::gradientInternalCoeffs( ) const
in file fields/fvPatchFields/basic/default/defaultFvPatchField.C at line 694.

FOAM exiting

I tried it where I declared just one input with 10 blocks or as 10 separate blocks in blockMeshDict and /0/U and /0/p. Same error.

I'm sort of committed to this 10 block idea, so I'm stuck and need some guidance.

I'm an absolute rookie on C++ (be gentle). The relevant member function of my parab....C file follows:

void parabolicVelocityFvPatchVectorField::updateCoeffs( )
{

const vectorField& c = patch().Cf();
scalarField cy = c.component(vector::Y);
scalarField cx = c.component(vector::X);
scalarField coord = (cx*cx+cy*cy)/0.0001;
vectorField::operator=(n_*maxValue_*(1.0 - (coord)));
}

(my radius is 0.01)


If anyone could help me, I'd be very grateful. If you need more stuff, too, I can pack it up and send it.

Thanks,

LEO

hi all,
i am very new to OpenFoam and needs an explanation on how to get the cell expansion ratios(simple grading)correct in icoFoam?i am working on a case with 2 inlets and one outlet with a no. of cells approx. 100,000.it is 2-d.
thanks in advance

I try to wmake parabolicVelo

Would someone give me a complete zip files?
In fact, I am trying to make a nonuniform wind profile, is this program the good one to modify?
Thanks a lot.

[sega]

Hello again.

Is any of these tools capable of setting a parabolic inlet velocity in y-direction?
One of the first messages stated, that this is setting a profile in x-direction ...

I need a parabolic inflow boundary in U for my nucleate boiling case. The gas is flowing through a hole in the bottom, so I don't have to simulate the evaporation itself ...

http://therealsega.th.funpic.de/openfoam/nb.mpg

[gschaider]

There are two options:
- you turn your geometry so that the inlet points in the right direction
- you replace Y wit X and vice versa in the utility (it's not THAT hard)
But writing (and publishing) a separate utility for every direction in space sems a bit of an overkill to me

Bernhard

[sega]

Hello!

For switching Y and X inside the utility I will have to take a closer look at it. Unfortunately I haven't worked with C++ before. But I will try.

Meanwhile: Do you think I can manage a parabolic distribution with your funkySetFields tool?
Or is it restricted for "internal" fields?
