You have to add "-lgslcblas" to the libraries in the option file. Unfortunately, the cblas interfaces have been outsourced into a separate library.

I will add the missing dependency to the repository as soon as possible.


Good Luck

Dear Matthias,

Thank you, I did as you suggested and included "-lgslcblas" after "-lgsl" in the options file, but some of the errors still remain.
When I run applyPatches, the following message appears indicating it is working properly (I suppose!):

Dear Syavash,

as long as you don't need the turbulence models in the library you can ignore these errors. The library seems to be correctly build.

There are some missing dependencies in the original turbulence models class of OpenFOAM. I have to modify the applyPatches to add these dependencies but this needs some time. I will do it till end of the week.

Dear Matthias,

I appreciate your comment, but the problem still persists when running solver "pisoFoam".
I have added inlet boundary condition as follows:

INLET
    {
    type decayingTurbulenceInflowGenerator;
    direction 1;
    LField uniform 0.00315;
    refField        uniform ( 6.355 0 0 );
    value           uniform ( 6.355 0 0 );
    }

I think it's OK, but when I run pisoFoam solver, the following message appears:

It can be seen that OF does not recognize inflowgenerator B.C.

Another question, Shouldn't I add something to controlDict??!

P.S.: Isn't it strange that other people did not encounter such problems as I did??!

Knock, knock, Great!

The problem was that I should have added the following line to the controlDict,

libs            ("libLEMOS-2.3.x.so");

Dear Matthias and Hannes, Thank you.

Hi amanbearpig,

I am trying to generate turbulence at the inlet for a flatPlate LES case. I am using the inflowGeneratorBC at the inlet. Is it possible to share your flat plate case in which you used the inflowGeneratorBC.

Many Thanks,
Abhi.

Just prescribe an appropriate uniform distribution of the Reynolds Stresses and the length scales. The generated length scales are isotropic anyway.

Regards, Hannes

Dear Hannes,

When I input a non-zero value as uv Reynolds stress, OF gives an error.
Is LeMOS supposed to accept non-isotropic inlet conditions??!

Thanks
Syavash

[openfoammaofnepo]

Hello Syavash,

What kind of problem do you have when you use non-isotropic BC there? For my experience, it is OK.

Hi,
By non-isotropic I meant that it is not possible to have non-zero values on non-diagonal columns of the stress tensor. Is it possible in your case??!

Dear Matthias,

I have successfully installed LeMOS on several PCs. On the last system I could also install LeMOS without any problem but when I run the solver (pimpleFoam), I get the following error:

[matthias]

Dear syavash,

you need to install the gsl and gsl-devel libraries on those systems. Some tools in the LEMOS lib require gsl support.


Good luck

Hello!

I would like to bump up the request by Abhi for a working test-case for a flat plate BL or some other simple flow.
Can anyone who succeeded in using the generator share one ?

Best,
Tim

We will have a look at it and publish a workaround as fast as possible.

Dear Matthias,
First off thanks for your posts in this thread. I was wondering to know if there is any possibility to modify the inflow generator code such that it writes vortons and R values in separate files rather than writing them in U. Do you have any suggestions to where i need to look inside the code?
Thanks a lot, beforehand.

Hi Ali,

please have a look at your modification of the code
https://github.com/ETH-BuildingPhysi...-OFTools-2.3.X
You will find it in the folder BC/LEMOSinflowGeneratorMod

It writes vortons into a separate file. In addition, in can interpolate input data. Example input data is found in BC/LEMOSinflowGeneratorMod/boundaryData/inlet

You might also be interested in the filtered noise inflow generator (Klein at al, Xie and Castro) in the folder BC/FilteredNoiseInflowGenerator

Kind Regards
Marc

Dear Marc,

do you mean that in your shared codes, the inlet related data will be put in a separate "boundaryData" under the time directory? The files include L, ref, Rs? Thank you.

[marc.immer]

the data goes into: constant/boundaryData/inlet where "inlet" is the patch name of your inlet boundary condition.

The same code/structure of the timeVaryingMappedFixedValue BC is used, see for example
OpenFOAM-2.3.x/tutorials/incompressible/simpleFoam/pitzDailyExptInlet

There is just no additional time directory for the LEMOS mod BC

Cheers
Marc

Ps: if a LEMOS maintainer is reading: feel free to copy paste from our modification. We would welcome if some fixes would go into the original version

Thanks for the suggestion but we are working on a new version of the inflow generator which improves the treatment of vector fields at the inlet, i.e. conservation of zero divergence , enhanced anisotropy features etc. At the moment, there is little effort to update the current implementation since the new one will be available in the short to medium term.


Best regards

Matthias

Hi Mark!
Thanks a lot! You are a life saver! I did download your package and checked out as development however I couldn't install this because it as soon as I run the Allmake code it just gives me the error of " unexpected ")" ". I removed all parentheses in the Allmake files, and replaced them with curly brackets (also I tried quotation marks) and now it says cannot find the paths! Any input?

Again thank you so much for this!

Dear Marc,

Could you please give the full information about the reference for filtered noise inflow generator? Thank you.
